The ex-Nerazzurri player completed a switch to the Citizens during the 2012 summer transfer window for a fee of €4 million [£3.2m], and his representative is adamant talks about him returning to his former club have no base.
"A return to Inter is impossible, absolutely impossible. He gave seven years to the Nerazzurri and even if you can never say never in football, a return for Maicon doesn't seem possible," he told Interlive.it.

Calenda also commented on the limited number of appearances that the 31-year-old has made at his new outfit, blaming injuries for his lack of action.
"He injured his heel in the first game of the Champions League against Real Madrid, that is the only reason why he has missed so many games," Maicon's agent said.
"When he has been fit, he’s always been a first team starter and he’s offered some excellent performances. I went to see him for the Manchester derby and he’s settled in really well," he added.
Maicon spent six years at Inter, before signing with the Premier League title holders in 2012.
