Zlatan Ibrahimovic scored his first goal for AC Milan since rejoining the club as they eased past Cagliari.
Rafael Leao had given the Rossoneri the lead just after half-time before Ibrahimovic, starting for the first time since his return, doubled their advantage with a left-footed strike.
The former LA Galaxy and Sweden striker had another goal ruled out for offside.
Ibrahimovic, 38, signed a six-month deal at the Serie A side in December, with the option of another season.
He scored 42 goals in 61 league games for the club between 2010 and 2012.
It was AC Milan’s first win since early December and they remain 20 points behind league leaders Inter Milan.
