Milan are flying high, but also concerned that Alexandre Pato could be out for two weeks with a thigh strain.
The Brazilian suddenly pulled up mid-sprint during last night's 3-0 victory over Sampdoria.
He was clutching the back of his right thigh and there is a suspected strain, but more tests are needed.
Reports from the Rossoneri camp vary from those who suggest it is only a twinge to others who claim this is yet another thigh strain.
Pato has struggled with muscular problems throughout the season, so the club medics must be wary of doing further damage.
It seems certain he'll miss Wednesday's Coppa Italia semi-final against Palermo, while there are real doubts over the upcoming Serie A games with Brescia and Bologna.
It's a problem for Coach Massimiliano Allegri, as Zlatan Ibrahimovic still has another two rounds to go on his three-match Serie A ban.
This would leave Robinho and Antonio Cassano as the only available strikers, though Pippo Inzaghi is nearing fitness after undergoing knee ligament surgery earlier this season.
Christian Abbiati also limped off during the Sampdoria game, but has only picked up a slight problem and is expected to be fit for Wednesday.
