Maicon's agent believes Chelsea will be among the teams who attempt to lure the defender away from Inter Milan this summer.
The Brazil international has been strongly linked with a move to Real Madrid but the Blues are also in the running for the 27-year-old wing-back.
Agent Antonio Caliendo claims Carlo Ancelotti is a big fan of Maicon but has warned the Blues boss he will have to pay to get his man.
'I believe Ancelotti is one of Maicon's biggest admirers,' Caliendo told Sky Italia.
'It's not just Real Madrid but Chelsea who also could make a move (for Maicon).
'I'm not saying that would be the case because the possibility (of buying the player) is open to every club.
'However, what I would like to point out is that you don't negotiate for a champion, you go there, you buy him and that's that.
'You need to make a financial effort to buy a champion.'
Inter president Massimo Moratti confirmed yesterday that there was a 50 per cent chance Maicon would leave the club this summer.
And Caliendo believes Inter are correct to evaluate the offers for the player before making a decision on whether to sell him.
'There's still a 50% chance,' said Caliendo. "We adapt to what
the(club) president wishes as he (Maicon) is tied to a four-year contractwith the club.
'Moratti has made the right decision by listening to offers.'
