Patrick Cutrone secures Milan derby win in Coppa Italia

The sides could not be separated in normal time and then the teenage forward struck in the 104th minute, running on to Suso's through-ball to slide it home.

Cutrone had come on as a substitute 15 minutes from the end of normal time - and he also picked up a yellow card for removing his shirt during his goal celebration.

His goal secured Milan a place in the semi-final where they will face Lazio.
