Mark Van Bommel was one of the key figures in last night's win over Napoli, but the agent admits his Milan future “is uncertain.”
The Dutchman arrived from Bayern Munich in January, but has no contractual obligation to stay at San Siro past June.
“What happens next year is uncertain and there are no guarantees,” agent Mino Raiola told Voetbal International.
“If Milan decide to keep Mark, then he will stay here.”
Among others, Van Bommel has been linked with PSV Eindhoven and Tottenham Hotspur.
The 33-year-old was sent off on his Serie A debut and is unavailable for Champions League competition, but has become an essential figure for the Rossoneri midfield.
