"Yes, there is interest from Real Madrid. But it is not only Los Blancos, because Maicon is the number one in his position," agent Antonio Caliendo said in Teleombardia.
Real prospected chairman Florentino Perez is reportedly aiming to bring in a number of high-profile stars, including Maicon, at the Bernabeu.
Maicon managed to make a name for himself over the past few years as he deservedly filled in the void left by Cafu's retirement in the Brazil roster.
He is expected to be out for up to a month with a thigh injury after he was stretchered off in the Selecao's 1-1 draw in Ecuador at the weekend.
The 27-year-old has proven to be one of the most consistent players in Jose Mourinho's side this season, featuring in 28 games out of 29 in the Serie A.
