The Frenchman didn't take long to make his mark in his first outing for the Italian giants against Nice
Olivier Giroud scored four minutes into his Milan debut following his €2 million switch from Chelsea earlier this summer.
Giroud signed a two-season contract with the Rossoneri upon his arrival at San Siro earlier this month, bringing to an end his four-year spell at Chelsea.
The 34-year-old was handed his first appearance for Stefano Pioli's side in a pre-season friendly against Nice on Saturday, and didn't take long to make his mark.
