Beşiktaş or Draw — 74% confidence
Besiktas have maintained a perfect home record with three wins and zero goals conceded in their recorded home fixtures, establishing strong stability on their own ground. In contrast, Marseille enter this contest having lost their last two competitive matches, including an away defeat at Monaco. Backing the hosts to either win or secure a draw provides sensible coverage given their current defensive solidity and Marseille's recent defensive vulnerabilities.
Yes — 63% confidence
Despite Besiktas maintaining a solid defensive record at home, Marseille possess significant offensive quality, having scored ten goals across their last five matches. Marseille have also conceded in four of their last five matches, including three in their recent home loss to Paris FC. With Besiktas scoring in each of their last three games, both teams have the attacking tools to find the back of the net.
These two calls are about different parts of the match (double chance and both teams to score), so neither one determines the other. The figure shown is the lower of the two — a combo can never be more likely than its weaker leg.
