Inter Milan president Massimo Moratti claims Real Madrid 'haven't done enough' to snap up Maicon.
The Spanish giants have been tracking the Brazilian full-back all summer, keen to add him to their galaxy of stars.
The interest has come as no surprise to all concerned, with former Inter boss Jose Mourinho having taken the reins at Santiago Bernabeu.
The Portuguese coach is known to be an admirer of Maicon and would welcome the opportunity to work with him again.
However, Moratti insists the Samba star will be going nowhere unless Real start taking the matter more seriously.
He told Corriere dello Sport: "Maicon remains with us. Real Madrid haven't done enough to take him. If they want Maicon, they should do more."
It remains to be seen whether Real will up their efforts to snare the 29-year-old, with the club's transfer consultant Ernesto Bronzetti hinting that they could be about to turn their attention elsewhere.
"There has never been a proper negotiation for Maicon," he told Sky Italia.
"I speak with (president) Florentino Perez every day and he hasn't spoken about Maicon for some weeks.
"The president wanted to sign him, but felt Inter's request was too high for a 29-year-old and there has been no counter offer.
"The deal for Maicon seems to be closed and Real will now follow players who aren't playing in Italy.
"I don't think Inter have made the most of the situation, because there are no other clubs interested in the Brazilian."
