The German international is currently on his fourth loan spell upon his arrival at Chelsea in 2012 and a first-team place at Stamford Bridge looks highly unlikely anytime soon and with Mourinho looking to have a squad overhaul in January Marin will be keen on plying his trade permanently for Trabzonspor.
According to AMK, Marin is now focusing on staying in Turkey, insisting he feels he can find success with Trabzonspor, who lie tenth in the Super Lig.
‘I came here to become a champion and I want to be part of the big plans we have here.
‘We are not where we want to be in the league, but we will turn things around,’ he said.
Marin featured on just 15 occasions for Chelsea in total, scoring one goal back in the 2012/13 season.
Chelsea are currently 16th in the premier league with just 11 points out of the 12 games played, the Blues most recently suffered a 1-0 loss away at Stoke last Saturday.
Mourinho seems to have big plans for Chelsea during the transfer window with speculation going around about a deal for Mercurial strikers Antoine Griezmann and Aleix Texieria.
