Marko Marin has left Chelsea for Olympiakos after signing a three-year deal with the Greek side.
The 27-year-old's move away from London was confirmed on Tuesday after Marin underwent a medical at Olympiakos a day earlier.
Marin, who can play as both a winger and a central midfielder, signed for Chelsea from German club Werder Bremen for £6.5million in 2012.
