FC Sion vs AFC Ajax: guide to the play-off night at Stade Tourbillon
FC Sion and AFC Ajax meet on 20 August 2026 at 20:15 at Stade Tourbillon in Sion, in the first leg of the Conference League qualifying play-off. The return leg is on 27 August in Amsterdam. The winner of the tie advances to the league phase of the competition, so the result in Sion will not finish the job, but it can strongly determine how both teams will approach the second match.
Sion enters the clash in very good form. After a league defeat to BSC Young Boys in the season opener, Didier Tholot's team put together a run of good results across the domestic league, qualifiers and cup. The home run is particularly important: after the 3-2 victory against FC Vaduz, the club announced that Sion had reached 16 consecutive league matches unbeaten at Tourbillon.
Ajax arrives in a different rhythm. Míchel Sánchez's team opened the league campaign with a 2-0 away win at PEC Zwolle, then drew 2-2 with Shelbourne FC in Dublin and progressed thanks to a 3-1 victory in the first leg, while last weekend at home it surrendered a 2-0 lead against sc Heerenveen and finished 2-2. Ajax therefore arrives with enough attacking quality to control the match, but also with a warning that having a lead does not guarantee security.
Tickets for this match are in high demand among supporters. FC Sion adjusted the sales schedule for the game, while the stadium will be fully configured with seating, reducing the available capacity of the north stand.
What is at stake for both teams
This is not a league round in which lost points can be made up a few weeks later. The play-off is played over two matches. Sion has home advantage for the first 90 minutes, while Ajax knows that it will play the return leg in Amsterdam. The ideal scenario for the home side is to travel to the return leg with a lead, but without opening up spaces that Ajax can punish with quick combinations and runs from deep.
In the domestic league, Sion is fourth after three rounds with six points, with two wins and one defeat and a goal difference of 8-6. Ajax is fifth after two rounds of the Dutch league with four points. The sample is still small, but both teams already have enough competitive minutes for their main habits to be visible.
In the previous qualifying round against FC Noah, Sion drew the first match 2-2 and won the return leg in Sion 2-1. Between those commitments it beat FC Vaduz 3-2 and then FC Kerzers 6-1 in the cup. Ajax reached the play-off by overcoming Shelbourne FC with a 3-1 victory in Amsterdam and a 2-2 draw in Dublin. According to FotMob, this will be the first meeting between FC Sion and AFC Ajax.
Form ahead of the clash
- FC Sion: 6-1 victory against FC Kerzers in the cup.
- FC Sion: 2-1 victory against FC Noah in the return leg of the previous qualifying round.
- FC Sion: 3-2 victory against FC Vaduz in the league.
- AFC Ajax: 2-2 draw against sc Heerenveen in the league.
- AFC Ajax: 2-2 draw away at Shelbourne FC after a 3-1 victory in the first leg.
Players who can shape the match
For Sion, it is worth starting with Winsley Boteli. Against Vaduz he scored with a header to make it 2-2 late on before Franck Surdez made it 3-2 in the fourth minute of stoppage time. Boteli is also among Sion's leading scorers at the start of the league season. His movement between the centre-backs and his attacking of crosses are particularly relevant against an Ajax defence that has conceded two goals in each of its last two matches.
Donat Rrudhani is also important for the home side. He scored with a volley against Vaduz, while his quality from set pieces and with the final pass gives Sion another route to goal. Ilyas Chouaref can carry the ball towards the final third, while Surdez has shown that he can decide a match from the bench as well. Didier Tholot therefore has several options for changing the rhythm in the second half.
At Ajax, the roles are distributed more widely. Youri Regeer is important for balance in midfield, Oscar Gloukh and Julian Brandt provide creativity between the lines, while Kasper Dolberg offers finishing in the penalty area. Abdellah Ouazane scored against sc Heerenveen, while Anton Gaaei found the net in Dublin against Shelbourne. The threat therefore does not come from just one area.
Ajax's squad changed during August through transfers and returning players, so it is more useful to follow the confirmed line-up than an early projection of the starting eleven. In the most recent league match, Míchel Sánchez started with Marc ter Stegen in goal and three midfielders behind the attacking line. That provides a good framework for expecting possession and patient build-up play, but it does not guarantee an identical line-up in Sion.
Tactical battle: Sion's transition against Ajax's possession
Sion is suited to moving the play forward more quickly. In a 4-2-3-1 formation it can leave two midfielders behind the ball and then attack the space behind the opposing full-backs through Chouaref, Boteli or Surdez. The moment when Ajax loses the ball high up the pitch will be particularly interesting. If the home side plays the first pass cleanly after winning possession, it can quickly find itself in a three-against-three or four-against-four situation.
Ajax will probably try to control the ball and the width of the pitch. Sánchez's team can build attacks in a 4-3-3 through the centre-backs and Regeer, then look for Gloukh or Brandt between the home side's lines. When the wingers stay high and wide, Sion's full-backs have to decide whether to step out aggressively or remain deeper. Each decision opens a different space.
For the home side, it will be important not to spend too much time on the edge of its own penalty area. Ajax has enough technically strong players to find an opening through repeated attacks. On the other hand, the visitors surrendered a 2-0 lead against Heerenveen and also conceded twice in Dublin. Sion therefore has reason to believe it will get its chances even after periods of Ajax control.
Set pieces could be an additional factor. Sion threatened several times from crosses against Vaduz, while Boteli and Kronig can attack high balls. Ajax will try to reduce the number of unnecessary fouls and corners, especially if the stadium gets into the game after early pressure from the home side.
Three duels worth watching
- Boteli against Ajax's centre-backs - movement in the penalty area and attacking crosses.
- Chouaref against the right side of Ajax's defence - Sion's ability to use transition to get in behind an advanced full-back.
- Regeer and Ajax's midfield against Rrudhani and the home block - the battle for space in front of the defence.
Absences and squad status
For Sion, Benjamin Kololli and Kreshnik Hajrizi were listed as injured at the beginning of August and were not in the squad for the league match against Vaduz. FotMob also lists them among the unavailable players ahead of the clash with Ajax. Since a player's status can change before kick-off, the confirmed line-ups will provide the final answer.
For Ajax, FotMob lists Ahmetcan Kaplan and Amourrich van Axel Dongen among the injured players ahead of the match. Steven Berghuis did not travel for the return leg against Shelbourne because of private circumstances, but subsequently returned and started the league match against sc Heerenveen. An older list of absentees should therefore not automatically be applied to this match.
Míchel Sánchez has enough depth to make changes. Against Heerenveen, Regeer, Davy Klaassen and Gloukh were in the starting line-up in midfield, with Berghuis, Dolberg and Ouazane further forward, while Jorthy Mokio, Brandt, Leonardo, Oliver Edvardsen and Tolu came off the bench.
Stade Tourbillon and the atmosphere
Stade Tourbillon is located at Rue des Echutes 38 in Sion. The stadium opened in 1968 and has been adapted to new requirements through several phases of reconstruction. FotMob lists a capacity of 14,283 for the venue, but FC Sion announced that for the match against Ajax the stadium will be fully set up with seating, meaning the number of available places in the north stand will be lower than for some domestic matches.
More important than the figure itself is Sion's run at this ground. After the victory over Vaduz, the club announced that it had gone 16 consecutive league matches unbeaten at Tourbillon. In previous qualifying matches this summer, the crowd has already watched Sion victories, so the home players enter the play-off without needing to adapt to the rhythm of such an evening.
Seats in the stands are disappearing quickly. For supporters planning to attend, the most important thing is to allow enough time to approach the stadium, as FC Sion had already warned before previous home matches that traffic in the immediate surroundings can quickly become congested.
Getting to the stadium
- The stadium address is Rue des Echutes 38, 1950 Sion.
- From Sion railway station to Tourbillon, the club states that the walk takes approximately 15 minutes.
- For arrival by car, the stadium is connected to the Sion-Est motorway exit.
- For larger home matches, FC Sion recommends parking by the hospital and using the pedestrian crossing towards the stadium.
- Visitors should expect congestion around the stadium and arrive earlier.
For the previous home qualifying match, which also started at 20:15, the club opened the entrances at 19:15, but the available club announcement about tickets for the match against Ajax does not state the same schedule. It is therefore not advisable to assume that the entrance times will be identical. The safest option is to arrive early and check the latest organisational information immediately before departure.
Sion is a city in the Rhône valley in the Swiss canton of Valais. Tourbillon is located east of the centre and close enough to the railway station for walking to be a practical option.
It is worth securing tickets in good time and arriving early to avoid congestion at the entrances.
What could decide the first leg
The first 20 to 25 minutes could show how willing Sion is to take risks. If the home side presses Ajax high, it can force the visitors into quicker decisions and energise the crowd, but it leaves space behind the first pressing line for Gloukh, Brandt or a striker dropping towards the ball. If Sion chooses a mid-block, the match could have a calmer opening, with greater emphasis on transitions.
It will be especially important for Ajax to manage the match after potentially taking the lead. The last two 2-2 draws show that its control of the scoreline has not been complete. In Sion, protecting a narrow lead too early could simply invite the home side to commit more players forward.
Sion's advantage is the energy from the bench. Against Vaduz, Chouaref, Surdez and Boteli came on during the second half, and it was Boteli and Surdez who scored the goals that turned the finish around. In a play-off this can be particularly important, because more space often opens up after an hour.
Ajax, on the other hand, has the depth to change the technical profile of its midfield and attack. Brandt can add passing control, Mokio dynamism, while Leonardo and Tolu can provide a different presence closer to goal. If the starting eleven does not find space against Sion's block, Sánchez does not necessarily have to change the system to change the way his team attacks.
Most important things before heading to Tourbillon
- Kick-off is at 20:15, and this is the first of two play-off matches.
- The return leg is on 27 August in Amsterdam, so the result in Sion should be viewed in the context of the entire tie.
- For arrival by train, the walking route from the station to the stadium is practical.
- For arrival by car, an earlier arrival should be planned because of possible congestion around Tourbillon.
- It is worth checking the confirmed line-ups and the status of injured players immediately before kick-off.
Ticket sales for this match are ongoing. On the pitch, Sion will try to exploit its home run and quicker transitions, while Ajax arrives with a greater amount of individual creativity and a clear desire to control the rhythm through possession. For a spectator in the stands, the most interesting moments could come precisely when one team loses control: after Sion wins the ball and breaks forward quickly, or after Ajax regains possession high in the home half.
