The 32-year-old is one of the most decorated goalkeepers in the history of professional football, winning 21 major trophies with Barcelona.
He was also part of the Spain squads that won the 2010 World Cup and Euro 2012, and holds the record for most appearances made by a goalkeeper in La Liga for the Catalan club.
Despite all his success, the Spaniard left Camp Nou over the summer for the first time in his career. Having announced his intention to leave Barcelona, the stopper tore his anterior cruciate ligament in a league fixture in March, ending his club involvement prematurely - and stopping his chance of signing for a club over the summer.
In recent weeks it was reported that Premier League side Liverpool were attempting to secure the ‘keeper’s services as a replacement for the struggling Simon Mignolet, but, after the Reds pulled out of any deal, Valdes starting training with their top flight rivals Manchester United.
He has continued training with Louis van Gaal’s side, and, when he returns to full fitness, it is expected that the stopper will be offered a contract by the Red Devils to resume his playing career.
For Man United, they will know that they are signing the goalkeeper recently named the greatest ever in La Liga history, according to the Spanish Centre for Football History and Statistics. The CIHEFE have analysed the careers of every ‘keeper to have graced the Spanish top flight since 1928, and Valdes came out on top. The study incorporated a number of factors, including goals conceded, titles won, consecutive clean sheets, total appears, and the number of Zamora Trophies won.
Valdes clinched first place ahead of the stopper he could be facing in the coming months should he agree a deal at Old Trafford - Chelsea’s Thibaut Courtois. Despite only playing in La Liga for three seasons with Atletico Madrid, the 22-year-old was named in second place, but there is no doubt that he is on the path to becoming a better keeper than Valdes was during the peak of his career.
