Barcelona have reached an agreement with Valencia to sign left-back Jeremy Mathieu for €20m, the Catalan club have announced.
The Frenchman is set to sign a four-year deal at the Nou Camp and will provide competition for Jordi Alba on the left side of defence. "FC Barcelona and Valencia CF have reached agreement for the transfer of the French player, Jeremy Mathieu," read a statement on www.fcbarcelona.com.
"Jeremy Mathieu will sign a contract with FC Barcelona for the next four seasons, plus an optional season more. The cost of the transfer is 20million euros (£15.8million) and the buyout clause will be 50million euros."
Mathieu travelled with the Valencia squad to Madrid as a stop off on their way to Peru as part of their pre-season tour, but will now travel to Barcelona to sign his contract with the Catalans and join Luis Enrique's side for pre-season training.
The Frenchman came through the ranks at Ligue 1 side Sochaux, making his professional debut in 2002 and eventually moved to fellow French side Toulouse in 2005. Four years later he swapped France for Spain to join Valencia, where he alternated between the left-back spot and centre-half, excelling in the latter position last season once Juan Antonio Pizzi took charge.
Although Mathieu will be able to deputise for Alba, he is likely to also play as centre-back and cover for the loss of captain Carles Puyol, who retired from football at the end of last season. Mathieu is the first central defender Barça have signed since Dmitro Chigrinski, who joined the club from Shakhtar Donetsk in 2009 for €25m only to return to the Ukranian side a year later following an unsuccessful stay at the Nou Camp.
Barça midfielder Rafinha Alcantara welcomed the signing of Mathieu, telling a press conference: "Mathieu is a complete defender, with incredible speed. He's a great centre-back."
