Manchester City will listen to offers for Maicon, 31, the Daily Mail reports.
The right-back arrived from Inter Milan last summer for £3million with a glowing reputation, but is now third choice at the club due to Pablo Zabaleta's form and Micah Richards' return from injury.
The Brazilian is reportedly on £100k-a-week so Manuel Pellegrini is thinking of letting the player go for a reasonable sum.
Another full-back who could be on their way out of Manchester is United's Alex Buttner, with Galatasaray and Besiktas showing interest.
