Olivier Giroud made a dream start to life at AC Milan as he scored twice on his home debut to help the Rossoneri to a 4-1 victory over Cagliari.

Around 40,000 fans were back in attendance at Milan's iconic San Siro stadium, and they were treated to a special opening first-half in which there were five goals scored, the opener an absolute beauty when after 12 minutes, Sandro Tonali curled a free-kick past Boris Radunovic at his near post.

Alessandro Deiola restored parity three minutes later, but less than 120 seconds after that, Rafael Leao's heavily deflected effort off team-mate Brahim Diaz restored the home side's lead.
