Chelsea complete move for Marin
The Blues announced on their website that they have agreed an undisclosed fee and the 23-year-old Germany international has agreed personal terms. Marin will join Chelsea at the end of the season.
Marin, who joined Werder from Borussia Monchengladbach in 2009 and was contracted to the club until June 2013, has already passed a medical in London and will sign a contract with the Blues in the next few weeks, according to his current club.
Speaking ahead of Werder's Bundesliga match with Wolfsburg on Saturday, Marin said he cannot wait to play in the Premier League.
"I had a really good time with Werder together with many great guys here, and I have lots of nice memories, but of course I am looking forward to the challenge of playing in the Premier League with such an established club," he said.
Marin made his Germany debut in 2008 and was part of their 2010 FIFA World Cup™ squad. However, he has spent much of this season on the sidelines due to injury and is not assured of a place in Joachim Low's squad for UEFA EURO 2012.
Werder's director of sport Klaus Allofs said in a statement: "We have always said that we would be open to talk if any of our players receives a good offer which was also interesting for Werder and we had good talks with the management at Chelsea, so that we were able to reach an agreement quickly.
"In the coming weeks, we will then deal with the last formalities. We wish Marko all the best for this new challenge."
