Barcelona centre-back Marc Bartra will join Borussia Dortmund after the German club agreed to pay his release clause, the Spanish champions announced on Friday.

"FC Barcelona announce that German club Borussia Dortmund have informed them of their desire to activate the buy out clause for the player Marc Bartra, according to which the Club is obliged to facilitate the transfer of the player for the price of 8 million euros ($9m)," Barcelona said in a statement on their website.

The Catalan daily Sport said the 25-year-old Bartra, who is in Spain's Euro 2016 squad, will sign a five-year deal with the Bundesliga side.

Bartra came through the ranks at the Camp Nou and was handed his top-team debut by Pep Guardiola in 2010.

However, he found first-team football hard to come by under Luis Enrique in the season just finished as Barcelona won the double of La Liga and Copa del Rey.

His departure follows the announcement that Brazilian right-back Dani Alves, 33, will be allowed to leave this summer.
