But he insists this doesn't mean he will slip away.
“Inter have made him feel important and given him the necessary support, so Marcelo has now become mature as a man as well as a player," agent Miroslav Bicanic told Vercenji List.
“He sees Milan as his home, as it's not far from Zagreb, so there's no need to put too much emphasis on these transfer rumours.
“If some of the biggest clubs in the world are ready to pay the €60m release clause, they must also agree terms with him. He is concentrated on Inter and battling with Juventus for the Scudetto."
