Milan head coach Vincenzo Montella has added a fourth new face to his squad with the capture of Andre Silva on a five-year deal from FC Porto.
The Rossoneri are preparing for their return to the continental stage for the first time in three years after qualifying for the Europa League.
Montella has already bolstered his options with the signings of Mateo Musacchio, Franck Kessie and Ricardo Rodriguez, with Silva the latest to arrive at the San Siro on Monday.
The 21-year-old striker scored 16 goals in 32 Primeira Liga outings to help the Dragons finish runners-up in Portugal to secure their place in the Champions League.
Silva is revelling in his dream move to MIlan, telling the club's official website: "This is a wonderful feeling. I'm really happy about this opportunity.
"I know the history of AC Milan and I know how big club it is. My dream came true that I can be here now, I will give it all I've got."
