Marko Marin – £6m
Pint sized German may well have wished he hadn’t moved to Stamford Bridge as he’s barely had a chance to impress since his move to the club back in the summer of 2012.
Marin signed a five year deal but has started just two Premier League fixtures and is currently on loan at La Liga side Sevilla.
The German international’s career is stagnating at Chelsea and a move back to the Bundesliga is now on the cards with the Premier League side looking for just £6m for the 24 year old.
