The Spain international was a star during his time at Barcelona and he decided to leave the La Liga giants as a free agent after the end of the 2013-14 season. In the final few months of his career at Nou Camp, he picked up an injury and was ruled out for lengthy spell.
Valdes was without the club at the start of the last season and Louis van Gaal gave an opportunity for him to train with the club. Earlier in January, the Red Devils signed Valdes and handed him an 18-month contract.
The ex-Barcelona stopper has not featured for United and has not been included in the Dutchman’s squad at Old Trafford for this season.
