Manchester City, Real Madrid, Inter Milan and Juventus are leading the pursuit of Monaco's Geoffrey Kondogbia, according to the player's agent Jonathan Benbaron.
Kondogbia, 22, has won three caps for France and attracted attention with his exploits as the French side reached the last eight of the Champions League.
And Benbaron revealed all four clubs have contacted him about the midfielder, who he believes could be transferred this summer.
"The player appeals to a lot of clubs around Europe," said Benbaron told FC Internews. "In addition to interest from Inter, there's also Juventus, Manchester City and Real Madrid. A lot of teams have contacted us, but I can't reveal how far along the various talks are.
"Will he leave this summer? Everything is possible in football."
Kondogbia, who has also been linked with Arsenal, is a former Sevilla player and has three years left on the contract he signed with Monaco in 2013.
City's need for midfield reinforcements increased when James Milner confirmed he is leaving to join Liverpool. They have already lost one midfielder, in Frank Lampard, and are interested in signing others, including Kevin De Bruyne and Paul Pogba.
