AC Milan insist there are no concerns over Alexandre Pato's long-term playing future.
Pato broke down again this week at Barcelona.
"All at AC Milan are strongly determined to solve in a positive manner and within the shortest timeframe possible the muscle problems of Alexandre Pato," read a statement released through the club's website.
"Numerous roads both diagnostic and therapeutic remain open and there is no doubt that the current situation will be overcome in a satisfactory manner. Pato will soon come back even stronger than before."
