Chelsea has announced the signing of Werder Bremen's Marko Marin for next season. A fee has been agreed with the two clubs while Marin has also agreed personal terms and will joint the club in the summer, according to a statement on the official Chelsea website.

Marin was in London this week, where he completed a medical, according to the Daily Telegraph. The paper also reports that Bremen want to take young Chelsea striker Romelu Lukaku on-loan for next season.

An attacking midfielder, Marin has been deployed predominantly centrally this season, but has spent much of his career on the left wing. He has won 16 caps for Germany.

The 23-year-old is known for his excellent dribbling skills and has also contributed five assists in 16 Bundesliga starts for Bremen this season. Marin has spent three seasons at his current club after moving from Borussia Monchengladbach.

Highly rated for a couple of seasons now, Marin has been linked with several of Europe's big clubs in the past, including Liverpool, but Chelsea have acted early to secure his signature this summer.

The announcement comes despite the fact that Chelsea still has yet to name a full-time manager. Interim boss Roberto Di Matteo is currently at the helm but, although he has led the club to the final of the Champions League, there is no word yet on the Italian being offered a contract beyond the end of the season.

It has been reported that owner Roman Abramovich will do everything in his power to persuade Pep Guardiola against taking a sabbatical from the game following his exit from Barcelona and instead take the reins at Stamford Bridge next season. That would appear to be an optimistic hope, however, with the 41-year-old seemingly clear on his need to take a break from the game.
