Champions League 2026/27 begins with major clashes: Real Madrid host Inter, Manchester City visit Porto
The league phase of the 2026/27 UEFA Champions League begins on Tuesday, 8 September, with the opening round spread across three days and featuring a total of 18 matches. The very first evening already offers three fixtures that stand out because of the names involved and their European tradition: Real Madrid - Inter, Porto - Manchester City and Borussia Dortmund - Villarreal. According to UEFA's official schedule, six matches will be played on Tuesday, six on Wednesday and six on Thursday, marking the start of the third season of the competition under the single-league format featuring 36 clubs. The first two matches on 8 September, AEK Atena - LASK and Club Brugge - Aston Villa, kick off at 18:45 Central European Summer Time, while the remaining four fixtures begin at 21:00. The league phase will run until 27 January 2027, when all 36 clubs will play their final, eighth matchday.
The opening of the new season comes after UEFA confirmed the final schedule for all 144 league-phase matches at the end of August. Each club plays eight matches against eight different opponents, four at home and four away, with all results contributing to a single league table. Under the competition rules, the top eight teams qualify directly for the round of 16, while the clubs finishing from ninth to 24th place will play additional ties for a place among the final 16. Teams finishing from 25th to 36th place are eliminated from European competition and do not transfer to the Europa League. Such a system makes every round important from the very beginning because points won in September can directly affect league position, the opponent in the knockout phase and the possibility of avoiding the additional play-off round.
Real Madrid and Inter open the season with a European classic
The match attracting the most attention on the opening night is the meeting between Real Madrid and Inter at the Santiago Bernabéu Stadium. Real Madrid states on its official website that the club is entering its 57th appearance in the European Cup or Champions League, more than any other team, and this will be the first of its eight league-phase matches. The Madrid team is coached this season by José Mourinho, who therefore faces in the opening round the club with which he won the Champions League in 2010 and completed a historic treble. Ahead of the match, Mourinho stressed that every point carries weight in this format, but also that his team does not want to view the fixture as merely one of eight, but as a match it wants to win. An additional symbolic dimension comes from the fact that Real and Inter are meeting in one of the most recognisable arenas in European football, at the beginning of a season in which both clubs have high ambitions.
Inter arrive in Madrid under the leadership of Cristian Chivu, and the Italian club confirmed that it completed its final preparations before travelling to the Spanish capital. At his press conference, Chivu said that he expects courage, personality and a desire to impose their own game from his team, while remaining aware of the difficulty of playing away at the Bernabéu. According to data published by UEFA, Real Madrid have won six of their last seven matches against Inter and have also won 19 of their last 21 matches against Italian clubs. Inter, on the other hand, have not won on their last 13 away visits to Spanish teams in UEFA competitions, although their attacking efficiency in the Champions League has been considerably better in recent seasons: they have failed to score in only two of their last 19 matches in the competition. The statistics give Real a historical advantage, but the start of a new season and changes on the benches add an extra degree of unpredictability to the clash.
Kylian Mbappé will also be at the centre of attention. UEFA states that the French forward enters the match with 70 Champions League goals and would equal Raúl González's tally in fifth place on the all-time scoring list with another goal. If he plays, goalkeeper Thibaut Courtois will make his 100th Champions League appearance, which would also represent an important personal milestone. According to UEFA's data, Real have won their opening match in 17 of their last 19 Champions League campaigns, so their tradition of starting the season strongly also favours the home side. Inter nevertheless arrive in Madrid after a good start to their domestic season, with Real's official match preview noting that the Milan club recorded three wins in the opening three rounds of Serie A. That makes this encounter more than an attractive pairing on paper: it is the first serious test for two teams that want to immediately establish themselves in the upper part of the single league table.
Porto against Manchester City: a difficult start for the English representatives
Manchester City begin their new European campaign at the Dragão Stadium, traditionally one of the more demanding away venues in Portugal. Ahead of the match, City coach Enzo Maresca described Porto as a team with a clear style, aggressive both with and without the ball, and particularly emphasised the home side's strength on their own ground. According to UEFA, Porto have lost only one of their last 14 home matches in European competitions, recording ten wins and three draws. At the same time, the Portuguese club have a considerably more modest recent record against English teams, with only two wins in their last 16 such encounters. That contrast neatly describes a match in which Porto are relying on home advantage and continuity, while City arrive with greater individual quality and experience of matches at the highest level.
For Manchester City, the match in Porto will be their landmark 150th appearance in the European Cup and Champions League, according to UEFA statistics. The English team have a favourable overall record against Portuguese clubs, but lost their most recent such encounter 4-1 to Sporting in the league phase of the 2024/25 season. Even more importantly for Maresca, City have lost six of their last nine away matches in the Champions League, demonstrating that European away fixtures in recent seasons have not been routine even for a team with so much quality. Maresca therefore stressed in his preview that City must retain their own identity and try to impose their game regardless of the atmosphere and the way Porto press their opponents. In a match in which both teams have clear reasons for caution, the opening goal could strongly influence the rhythm and tactical shape of the contest.
Erling Haaland will once again be one of the English team's main threats. Ahead of the match, Manchester City announced that the Norwegian forward had scored three goals in his first three league appearances of the new season, while Maresca highlighted his importance in the team's attacking structure. At the same time, he acknowledged that he will have to manage the playing time of key players carefully during the congested schedule, which is particularly important in a season in which clubs are simultaneously competing in domestic competitions and eight Champions League league-phase matches. Porto will therefore try to restrict the supply of balls to Haaland and force City to attack through other channels. For the home side, a positive result against one of the competition favourites would have both practical and psychological value, because in the new format every point against a top opponent could later prove decisive.
Borussia Dortmund host Villarreal with a warning from last year's experience
Tuesday's third major clash takes place in Dortmund, where Borussia host Villarreal. Ahead of the match, the German club point out that they defeated the Spanish side 4-0 at the same stadium last season, but coach Niko Kovač warns that such a result must not create a false sense of security. Borussia have started the new domestic season well, with the club's preview noting two victories in their first two Bundesliga rounds and a convincing passage through the German Cup. Villarreal, by contrast, according to the same source, have not yet found the form they showed last season, when they finished third in La Liga and secured another Champions League appearance. Kovač therefore stressed that reputation and current form are not enough to judge a team that has the quality to punish mistakes at European level.
UEFA's statistics further emphasise Dortmund's home strength against Spanish clubs. Borussia have lost only two of their last 15 home matches against teams from Spain, with nine wins and four draws, and have won their last three such encounters. Villarreal, on the other hand, have recorded only two victories in their last ten matches against German clubs. Nevertheless, in recent years the Spanish team have shown that their Champions League matches rarely remain closed affairs: none of Villarreal's last 31 matches in the main stage of the competition have ended goalless. All of this suggests a contest in which Dortmund have the statistical and home advantage, but will need to control transitions and avoid opening space for their opponents.
Six matches on the opening day and a wide range of stories
The programme on 8 September is not limited to the three most high-profile pairings. AEK Atena and LASK open the evening at 18:45, and UEFA notes that the Greek club are returning to the main phase of the Champions League for the first time since the 2018/19 season. AEK have won nine of their last 11 home European matches, while LASK are making their first appearance in the league phase or the former group stage of the Champions League. The Austrian champions reached a place among the top 36 after a dramatic qualifying campaign, including a 5-1 victory against Celtic in the second leg of the play-off, which ended a run of 11 European matches without a win. The match therefore brings together a returning side in Europe's elite competition and a debutant for whom qualification itself is already a historic achievement.
The opening round continues on Wednesday and Thursday
The Champions League continues on Wednesday, 9 September, with another six matches. Barcelona host Feyenoord, Stuttgart play Viking, Liverpool welcome Atlético de Madrid at Anfield, Paris Saint-Germain face Slovan Bratislava, Sporting CP play Galatasaray, and Napoli meet Arsenal. Particular attention will be focused on Paris, who enter the competition as reigning champions and, according to UEFA, are attempting to become only the second team in the Champions League era to win three consecutive titles. Liverpool and Atlético meet again in the opening round after last season's clash at Anfield, while Napoli and Arsenal begin their campaigns with a meeting between two clubs that have ambitions to finish high in the single league table. Wednesday therefore continues the pattern of a season beginning without a long warm-up period: several traditional European clubs immediately face each other.
On Thursday, 10 September, the first round concludes with Fenerbahçe - Roma and PSV Eindhoven - Šahtar Donjeck in the earlier time slot, followed by Como - Leipzig, Bayern München - Bodø/Glimt, Manchester United - Sabah and Slavia Prag - Lens at 21:00. The return of Manchester United to the Champions League particularly stands out in this group, as does Bayern's home run in the league phase and former group stage. UEFA states that Bayern are unbeaten in their last 38 home matches in that phase of the competition, with 36 wins and two draws, and have also won their opening fixture in each of their last 22 Champions League campaigns. Bodø/Glimt, however, are no longer complete outsiders in the way their name might once have suggested, having reached the round of 16 in their debut appearance last season. The new format gives precisely such pairings an additional dimension: clubs from different footballing environments receive more opportunities each season for direct encounters with Europe's giants.
A single league table increases the importance of every point
The league phase introduced in 2024/25 changed the way the beginning of the Champions League is viewed. Under the old group system, one poor result could be more easily compensated for in the return match against the same opponent, whereas now each team plays each of its eight opponents only once. UEFA regulations award three points for a win and one for a draw, with all 36 clubs ranked in the same table. The objective for the favourites is therefore not merely qualification, but also a place among the top eight, which brings direct entry into the round of 16 and avoids two additional play-off matches in February. For mid-ranking European clubs, on the other hand, the 24th-place threshold becomes crucial because anything below it means the end of their continental season.
The schedule adds further pressure because the eight rounds extend from September until the end of January, alongside domestic leagues, cups and international breaks. The second round is played on 13 and 14 October, the third on 20 and 21 October, the fourth on 3 and 4 November, followed by another four rounds through 27 January. As early as the second round, Manchester City host Paris Saint-Germain, while José Mourinho's Real Madrid visit Roma, another of his former clubs. This demonstrates how congested the schedule is and how quickly the major clubs enter a sequence of matches that can determine their position for the knockout phase. The opening round is therefore not merely a ceremonial beginning to the new European season, but the start of a race in which every point contributes to the single standings right through to the final evening.
Schedule for Matchday 1 of the 2026/27 Champions League
- Tuesday, 8 September: AEK Atena - LASK (18:45), Club Brugge - Aston Villa (18:45), Borussia Dortmund - Villarreal (21:00), Porto - Manchester City (21:00), Lille - Real Betis (21:00), Real Madrid - Inter (21:00).
- Wednesday, 9 September: Barcelona - Feyenoord (18:45), Stuttgart - Viking (18:45), Liverpool - Atlético de Madrid (21:00), Paris Saint-Germain - Slovan Bratislava (21:00), Sporting CP - Galatasaray (21:00), Napoli - Arsenal (21:00).
- Thursday, 10 September: Fenerbahçe - Roma (18:45), PSV Eindhoven - Šahtar Donjeck (18:45), Como - Leipzig (21:00), Bayern München - Bodø/Glimt (21:00), Manchester United - Sabah (21:00), Slavia Prag - Lens (21:00).
After just three days, all 18 matches of the opening round will have been played and the first complete league table of the 2026/27 season will be formed. Although it is still too early in September to speak of decisive points in a mathematical sense, the experience of the first two seasons under the new format has shown how much the final standings can depend on small differences. Real Madrid, Inter, Manchester City, Porto, Borussia Dortmund and Villarreal therefore enter the season with no room for a relaxed opening, because each of them already faces on the first evening an opponent who could have a direct impact on the distribution of places in the upper half of the table. For the other clubs, the opening week provides an opportunity to build an early advantage or win points against opponents they will not have another chance to face in the league phase. The competition's finale is scheduled for 5 June 2027 at the Metropolitano Stadium in Madrid, but the road to that final begins on 8 September with the first six matches of the new season.
