Robbo's Verdict

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

The model assigns an 89.6% probability to both sides scoring, making this the most confident market for the fixture.

Show the maths
Both clubs have an expected‑goals value of 3.0, meaning the combined xG for the match is 6.0. The model translates that combined figure into a BTTS probability of 89.6%, which is the highest confidence reading among the available markets. The identical xG scores also drive the over‑2.5 goal probability to 93 %, reinforcing the expectation of multiple goals and confirming the BTTS outlook.
Pick 2 · Both Teams to Score
Both Teams to Score — Yes Won 89.6% model probability

With FC Sion averaging 3.0 expected goals and Ajax averaging 3.0, the model gives a 89.6% chance both teams find the net, ahead of the 10.4% it gives to at least one side being kept out.

Show the maths
BTTS probability is derived from each side's expected goals (FC Sion 3.0, Ajax 3.0) run through the same Poisson goal-expectancy model used for the match result: 89.6% of simulated outcomes have both teams scoring at least once, versus 10.4% where at least one side is shut out.
Pick 3 · Total Goals
Over 2.5 Goals Won 93.0% model probability

Combined expected goals of 6.0 (FC Sion 3.0 + Ajax 3.0) points to an open game, with the model giving Over 2.5 Goals a 93.0% chance against 7.0% for Under.

Show the maths
Total goals probability comes from the same Poisson model summing both teams' expected goals (FC Sion 3.0 + Ajax 3.0 = 6.0 combined): 93.0% of simulated outcomes finish with 3 or more goals, versus 7.0% finishing with 2 or fewer.
Match Result Model

Our Poisson model, built from each side's real season scoring and conceding rates, has FC Sion at 41.3%, the draw at 16.7%, and Ajax at 41.3% to win.

Most Likely Scoreline

The single most likely scoreline in our model is 2-2 at 5.0% — treat any single scoreline price with caution given how spread out the probability distribution is across a low-scoring match.

Form Guide — Last 5

FC Sion

DWDW

Sion’s last five league results read D‑W‑D‑W, including a 4‑0 home win over Bate Borisov and a 2‑1 home victory against FC Noah. Those wins, especially the clean‑sheet 4‑0, show they can dominate at home, supporting the view that they will find the net against Ajax.

Ajax

WWWD

Ajax have been in striking form with three consecutive wins before a draw, highlighted by back‑to‑back 4‑1 away and home wins over Vojvodina and a 3‑1 home win versus Shelbourne. Their ability to score heavily on the road underpins the expectation that they will also score at Sion.
