Barcelona goalkeeper Victor Valdes has undergone successful surgery on his knee injury and is expected to be sidelined for seven months, the Catalan giants have announced.

Valdes tore the anterior cruciate ligament in his right knee during Barca's 3-0 win over Celta Vigo on 26 March. The injury occurred when he landed awkwardly while saving a free-kick.

The 32-year-old Spain international went under the knife in Augsburg, Germany, on Monday morning and Barca confirmed on their website the surgery had been successful.

Barca also announced that Valdes would likely be absent for seven months. Jose Manuel Pinto is now likely to start as Barcelona's first-choice keeper for the remainder of the season, with Oier Olazábal as his understudy.

A statement on read: "Victor Valdes has been operated on this Monday morning by doctors Ulrich Boenisch and Ricard Pruna in Augsburg on his torn anterior cruciate ligament.

"The knee's internal cartilage has been sewn up and the operation was concluded successfully. Valdes will be out of action for approximately seven months."

The injury means Valdes will not only miss this summer's World Cup finals in Brazil, but also that he is likely to have played his last game for Barca.

The long-serving custodian has long planned to leave the Camp Nou at the end of his contract in June.

Valdes has played 535 senior games for Barca since making his debut over a decade ago, and won six Primera Division titles, three Champions League crowns and two Copa del Reys among a host of other trophies.

He was also part of the Spain squad that won the 2010 World Cup and 2012 European Championships.
