Leao’s absence is another blow for Allegri, who decided to keep him at San Siro despite transfer interest from Bayern Munich and Barcelona this summer. The 26-year-old had been expected to return after the international break, with Bologna circled as his comeback game, but his setback again leaves Milan short of options in attack.
With Leao out, Allegri is likely to pair Christian Pulisic and Santiago Gimenez up front. Both attackers have just returned from international duty, while Gimenez will be looking to build on his confidence after scoring for Mexico in a friendly against South Korea.
Notably, Milan’s start to the season has been uneven. They were stunned in their opener by newly promoted Cremonese in a 2-1 defeat, but bounced back with a 2-0 victory over Lecce. Facing Bologna, who beat them in the Coppa Italia final last May, will be another tough test.
