Valdes signed an eighteen month contract with Man United last January but the Spaniard has been frozen out at Old Trafford following a disagreement with Louis van Gaal.
The 33-year-old has only made two appearances under van Gaal and it is likely that he will never play for the club again.
Celta Vigo, who are fourth in La Liga, are reported to be strongly interested in offering Valdes a way out of the Premier League.
Valdes has enjoyed a long and successful career at the highest level and it is a shame to see his career fizzle out in the way it has.
A move away in January would make sense for all parties involved as United would get an unhappy player off their hands while Valdes would see minutes on the pitch elsewhere.
