Manchester United have offered the former Barcelona goalkeeper Víctor Valdés the chance to complete his rehabilitation from a serious knee injury at Old Trafford.

The 32-year-old, who has been linked with a possible move to Liverpool, tore cruciate knee ligaments in March and is without a club after leaving the Camp Nou at the end of last season and United’s manager, Louis van Gaal, has given the free agent, who won six La Liga titles, an opportunity to train at the club.

A statement on Manchester United’s official website read: “Valdés, a free agent, will have his recovery supervised by the United medical staff before training with the first team, as he bids to regain full fitness.”

The club did not confirm whether the player would be offered a contract.
