The Brazilian full-back arrived at City last August but found first-team opportunities limited and he made just 11 appearances during the 2012/13 campaign.
A move that never really bore fruit.
Brought in by Roberto Mancini, the Brazilian was expected to be a key part of the evolution to a 3-5-2 formation with his ability to maraud forward. Fitness and injuries problems, combined with the form of Pablo Zabaleta and teething problems with adopting the formation restricted Maicon to just 11 appearances.
Maicon occasionally showed flashes, with the 3-5-2 in turn looking a threatening proposition but for both player and system there was never the consistency of use to ensure success. With the form of Zabaleta and return to fitness of Micah Richards (who can provide elements of the forward presence Maicon offered) as well as a change of approach under Manuel Pellegrini it meant Maicon was a superfluous presence in the squad.
His departure does also mean that City have managed to shed quite a sum off the books this summer to in part finance the players that have arrived.
