Victor Valdes might not feel like one, but despite a recent loan move to Standard Liege the Spaniard is still very much a Manchester United player.
He's still on their books and has a duty as a professional footballer to not use social media as a means of landing a cheap shot.
In his latest show of discontent, Valdes has hit out at the Red Devils after marking his debut with a win for Liege.

The former Barcelona shot-stopper tweeted on his personal account (see below): "Happy for first Win for Standard! and for play after 8 months working alone. Thanks to the Standard Supporters!"
The Spain international's somewhat childish swipe is sure to raise a few eyebrows and rid of any chance he had of a return to Manchester.
Following a trophy-laden career with both Barcelona and Spain, Valdes' purchase was seen as an inspired buy at Old Trafford, especially amidst the uncertainty surrounding David de Gea's future.
In truth, though, he was never going to succeed. His dismay at not being picked ahead of Sergio Romero as United's number two was clear to see, which ultimately saw him slide further down the pecking order under Louis van Gaal.
It seemed Valdes' time had come when Romero performed so poorly during a 2-1 defeat against Swansea, yet De Gea signed a new contract and was immediately reinstated as the club's number one.
The 34-year-old arrived at the Theatre of Dreams with an ego - one that suggested his success at Barcelona was deserving of a starting berth. Some 18 months later, however, and United are far better off without him and will likely sell to anyone willing to take him this summer.
For now, though, he has a very faint connection with Old Trafford and no matter how thin the allegiance, he has to refrain from voicing his opinions in a backhanded way.
