Ajax host FC Sion in what is essentially a showcase of the Dutch side’s attacking depth. After blasting Vojvodina 4-1 both home and away and a recent 4-2 win over Sion, Ajax’s firepower looks unstoppable.

Robbo's Verdict

Strong
Both teams to score - Yes Won Strong lean Strong · High BTTS probability

The model assigns a 74.6% chance that both Ajax and Sion will hit the net, making this the most compelling single market.

Show the maths
Ajax’s expected 3.5 goals versus Sion’s 1.5 yields an aggregate xG of 5.0, which translates into a very high likelihood of at least two goals being scored. The model’s BTTS probability of 74.6% emerges from combining Ajax’s strong home scoring record (3.5 per game) with Sion’s modest yet consistent away threat (1.5 per game). This xG gap pushes the win‑probability for Ajax to 74.0%, but the simultaneous scoring chances lift the BTTS metric well above the 70% threshold, confirming the bet’s strength.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes Won 74.6% model probability

With Ajax averaging 3.5 expected goals and FC Sion averaging 1.5, the model gives a 74.6% chance both teams find the net, ahead of the 25.4% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (Ajax 3.5, FC Sion 1.5) run through the same Poisson goal-expectancy model used for the match result: 74.6% of simulated outcomes have both teams scoring at least once, versus 25.4% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals Won 86.5% model probability

Combined expected goals of 5.0 (Ajax 3.5 + FC Sion 1.5) points to an open game, with the model giving Over 2.5 Goals a 86.5% chance against 13.5% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (Ajax 3.5 + FC Sion 1.5 = 5.0 combined): 86.5% of simulated outcomes finish with 3 or more goals, versus 13.5% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has Ajax at 74.0%, the draw at 12.7%, and FC Sion at 12.4% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 3-1 at 7.2% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.
