Manchester United and Chelsea are eyeing Inter Milan striker Diego Milito.

The agent of the Argentina international admits the forward could quit for the Premier League if Inter do not upgrade his existing contract.

Chelsea, Manchester United and Manchester City are all interested in Milto.

"The priority for Diego [Milito] is to stay at Inter, but if things turn out negatively then Inter should name a price as there is interest from clubs in England," agent Fernando Hidalgo said.
