Chelsea have confirmed that Germany international Marko Marin will join the club in the summer.
Reports in Germany have claimed that the Blues have agreed to pay Werder Bremen £6.5m for the 23-year-old's services.
The winger, who has featured on 16 occasions for his country, has also agreed personal terms over a move to Stamford Bridge.
Marin has made 21 appearances for Bremen this season, scoring one goal in the process.
It has been suggested that Chelsea will allow the German club to take Belgian striker Romelu Lukaku on a season-long loan as part of the deal.
