Victor Valdes, who won six La Liga crowns in his 13 years with Barcelona, as well as winners medals at the 2010 World Cup and Euro 2012 with Spain, is Middlesbrough's fifth capture since they gained promotion to the Premier League

Victor Valdes who only played two matches for the Manchester United F.C. will now join Belgium's Standard Liege on loan until the end of this season.

Spanish goalkeeper Victor Valdes left FC Barcelona for Manchester United F.C. last season.

Van Gaal said on Wednesday Valdes would be shown the door at Old Trafford after refusing to play for United's second team. Valdes took to twitter to criticise his manager.

Louis Van Gaal said former Barcelona keeper Valdes, who only signed for United in January, faced an early end to his Old Trafford career after failing to follow the club's philosophy.

David De Gea is expected to leave Manchester United this summer and join Real Madrid but Juan Mata is confident that Victor Valdes' experience is valuable to the Red Devils' squad.

Victor Valdes inked an 18-month contract with the option for a further year. The 32-year-old will be a backup to the team's first choice goalkeeper David de Gea.

The 32-year-old Victor Valdes, who left Barcelona at the end of last season after spending his whole career at the Catalan club, is recovering from a major knee injury which scuppered a proposed move to Monaco.
