Borussia Dortmund have agreed to sign Barcelona centre-back Marc Bartra.
Die Schwarzgelben activated the eight million euros release clause in 25-year-old's contract, which the La Liga champions cannot reject.

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."
The length of his contract at Dortmund has not been disclosed.
