Sion vs Ajax Prediction 20 August 2026
📢 Before the season started, one of the main goals of Sion's management was to reach the league phase of the Conference League. However, the Swiss club were clearly unlucky in the draw: in the final qualifying round they were handed Ajax - one of the most high-profile opponents they could possibly have met at this stage. Sion's chances of progressing are considered slim, but if the team can put in a decent performance at Tourbillon, the picture could change ahead of the second leg.
Head-to-Head
📊 Sion and Ajax have never met each other before.
Head-to-head statistics Sion - Ajax

Sion Team Overview
Sion had a very successful last season: the club finished fourth in the Swiss championship and earned a place in European competition for the first time since 2018. They have started the new season confidently too, picking up six points in the first three rounds, and last weekend thrashed Kerzers 6:1 in the first round of the Swiss Cup.
In the Conference League, Sion have already come through two qualifying rounds. Their opponents were not of the highest level - BATE and Noah - but even against them it was no easy ride. Against the Belarusian club, the Swiss unexpectedly drew on neutral ground (1:1), before winning comfortably 4:0 at home. Then came a tricky tie with the Armenian club: away from home, Sion fought back to draw with ten men (2:2), and in the return leg at home managed to progress (2:1), despite trailing at half-time.
Worth highlighting separately is the form of Winsly Boteli. The 20-year-old striker has made an excellent start to the season and has been involved in at least one goal - either scoring or assisting - in every league and European match. Ahead of the game against Ajax, he is one of the main threats to the opposition defence.

Ajax Amsterdam Team Overview
Ajax are one of those clubs it's hard to imagine European football without. Though the days when the Amsterdam side were one step away from a Champions League final are long gone. The club now find themselves having to start their European campaign in Conference League qualifying after a disappointing last season in the Dutch championship, where they finished fifth and had to fight their way into Europe through the play-offs.
The new season isn't going smoothly either: Ajax picked up four points from their first two league matches, and last weekend they let victory slip at home against Heerenveen (2:2). The team were leading 2:0 as early as the 33rd minute but ended up allowing their opponents to level.
In Conference League qualifying, though, the Amsterdam side have had few serious problems so far. In the second round Ajax thrashed Vojvodina 8:2 on aggregate, then got past Shelbourne (5:3 over two legs). Though it was a nervy evening in Ireland. So in the match against Sion it's important for the Dutch side not to underestimate their opponents.

⚽️ Goals Prediction
Sion have a lethal attack: the Swiss side have scored in 19 consecutive official matches - a run that stretches back to the end of last season. In a home game against Ajax, there is no point for them to sit back and try to hold a draw: in the second leg in Amsterdam, the Dutch will exploit any weakness in their opponents regardless. So the hosts will have to look for their own chances in attack. Based on this, we are backing Sion to score at odds of 1.52*.
🚩 Corners Prediction
For fans of set-piece betting, we can offer the option of Sion total corners over 3.5, which is available at odds of 1.55*. In their home game against BATE, the Swiss club took 10 corners, and against Noah - 7. Set pieces could also prove to be a great opportunity to score against Ajax, so the Swiss will certainly not be passing up that option.
🟨 Yellow Cards Prediction
There is no denying that Ajax players are considerably more technical and quicker. The Swiss club will struggle to keep up with their opponents in many situations and will repeatedly have to stop attacks with fouls, including at the cost of bookings. So a bet on Sion to receive more yellow cards is worth considering.
*Odds are indicative and may vary across different bookmakers.
⭐️ Editor's Pick
According to the bookmakers, Ajax are an overwhelming favourite even in a standalone away match. However, Sion should not be underestimated, as they know how to make the most of home advantage. In last season's national championship, the Swiss club more than once left the country's top sides with nothing. It was their big away win over St. Gallen late in the season that handed the title to Thun. So the Dutch side will clearly have a tough time of it too. Taking into account the hosts' scoring run, our editors have decided to go with both teams to score (yes). We'll take a risk and suggest the match ends 2:2.
