Borussia Dortmund have agreed to sign Barcelona centre-back Marc Bartra.

The Bundesliga club activated the 8m euros release clause in the 25-year-old's contract, which the La Liga champions could not reject.

Bartra has been at the Nou Camp since the age of 12 and worked his way through the youth system to the first-team, making 26 appearances in all competitions last season.

A statement from Barcelona's website said: "FC Barcelona wish Marc Bartra all the best in his new phase of his career as a player and he will be invited to say goodbye to the fans personally at the start of next season."

Dortmund have announced Bartra has signed a four-year contract.

probably a good move for Dortmund and Bartra, more first team football will help him a lot. could become one of the top CBs in the world...

bartra one of the best CB Na he got skinned by bale

^Yeah, but maybe we shouldn't forget that Bale is seen as the 5th fastest football/soccer player currently.^

@11bale Yeah thats true it's almost as if Bale isn't an extremely fast player...

^ football isn't all about pace. Bartra is meant to be a defender. Defenders are meant to be strong and not easy to get past . Bale outmuscled a defender while bale is just a winger. Bartra is weak physically too.
