A team superior to the "Supercomputer" predicts the UCL semi-final first leg result between Atletico Madrid and Arsenal.
On 29 April 2026 GMT+7, Opta, a leading football statistics expert, revealed predictions for the UEFA Champions League 2025-26 semi-final first leg second match before tonight's kick-off.
02:00 Atletico Madrid (Spain) VS Arsenal (England)
Opta's supercomputer predicts the away team, Arsenal, has a slightly higher chance of winning over the home team, Atletico Madrid, after the "Gunners" previously defeated the "Colchoneros" 4-0 at home in the league phase last October.
Previously, the two teams met in the 2017-18 Europa League semi-finals, where Atletico Madrid won on aggregate 2-1 (1-1 away draw, 1-0 home win against Arsenal).
This marks the 16th UCL semi-final meeting between Spanish and English clubs, with English teams having a better record, winning 9 out of 15 times (60%), including 4 wins in the last 5 encounters.
The supercomputer's prediction is based on calculating probabilities and simulating thousands of matches, analyzing multiple factors such as each team's past and current performance, latest team readiness, and betting market odds.
