Milan marked their return to Serie A action with an eventually comfortable 4-1 win over Lecce at the Via del Mare on Monday.
Samu Castillejo put the Rossoneri ahead in the 26th minute but Lecce equalised through Marco Mancosu's penalty after Matteo Gabbia fouled fellow substitute Khouma Babacar.
However, Giacomo Bonaventura and Ante Rebic, who was sent off in the Coppa Italia semi-final exit at the hands of Juventus on June 12, struck in the next three minutes to put Milan out of reach.
Substitute Rafael Leao put the result beyond doubt in the 72nd minute as the Rossoneri returned to seventh after Hellas Verona and Parma moved above them at the weekend.
