Chelsea have announced that they have a deal in place which will see Werder Bremen midfielder Marko Marin arrive at Stamford Bridge over the summer.
The Blues revealed on their official website that an undisclosed offer for the Germany international has been accepted.
Marin has also agreed personal terms with the FA Cup and UEFA Champions League finalists and will open a new chapter in his career in England once the Bundesliga season comes to a close.
The 23-year-old, who joined Bremen 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.
Speaking ahead of Bremen's 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 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 Euro 2012.
Bremen'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."
