AC Milan thrashed Juventus in Turin to leave last season’s champions battling to qualify for next season’s Champions League.
The two sides went into the game joint-fourth in Serie A after Napoli won on Saturday to move into third position.
Brahim Diaz gave the Milan club the lead right on the stroke of half-time.
Goals from Ante Rebic and on-loan Chelsea defender Fikayo Tomori then sealed victory to send Milan third.
Juve are now a point outside the top four with three games left, including the visit of newly crowned champions, Inter Milan.
