Manchester United could come to regret selling goalkeeper Victor Valdes if compatriot David De Gea gets his wish to join Real Madrid.
The former Barcelona goalkeeper made just two appearances for the Red Devils after signing in January, and had been tipped by many to don the number one jersey for this campaign.
However a bizarre dispute with Louis van Gaal put those hopes to bed, and he now leaves having never really made his mark at Old Trafford.

If De Gea is to depart for the Spanish capital, it leaves his manager with Sergio Romero, Sam Johnstone and Anders Lindegaard as the club's three goalkeepers.
Though he has three clean sheets to his name, Romero looks unconvincing, whilst Johnstone and Lindegaard were initially expected to leave at the start of the transfer window.
Van Gaal should have kept Valdes
Now, much to the annoyance of many fans, they seem to have a future at the club but Valdes would have been a much better option than any of them.
He is a goalkeeper with experience and ability - rare in the modern game - and one who played his part by helping Pep Guardiola's Barcelona to become one of the best sides in the history of the sport.
Even on the two occasions to impress he looked solid enough, making many spectacular saves to deny Hull City a goal on the final day of last season's Premier League campaign.
Besiktas are gaining a goalkeeper desperate for regular football after missing much of last term through injury, but Van Gaal was meant to be the manager to get his career back on track.
Valdes apparently refused to play for the Under-21's but the goalkeeper had been playing regularly up in the side prior to being given a starting berth in the wake of De Gea's injury late last season.
Meanwhile a shortage of genuine world-class goalkeepers mean there are no guarantees United will enter the market if last season's Player of the Year leaves for Madrid.
Now, Valdes looks like he will be plying his trade in Turkey. One of the best goalkeepers of the decade has plenty more to offer, but none of the European elite are clearly prepared to take that chance.
