A lot of hearsay and not much factual information behind your claims. Did he submit a transfer request? Wanting to go to Real Madrid and forcing a move to go to Real Madrid are two different things. Like I said, not bothered how much he's paid at all. When he was dropped for Henderson, did he cry to the press and start talking shit about the manager like some of the cry babies in the team this season? Nope, went to training and fought for his place instead. Couldn't careless about clauses to go to Real Madrid, it's how they perform for Man United that counts and he's saved our ass this season, multiple times including the other night and hasn't cried off once. He also didn't have to accept the contract offers put infront of him, he could've run down his contract but he didn't.
The other night, surely you're not serious? He was pathetic for the goal & then made a save from a long distance shot that you'd expect any PL keeper to make. There is the bizarre narrative around him at the moment where every time he makes a save it's supposedly outstanding when in reality - like most goalkeepers by the way - 95% of his saves are regulation stops. I'm all for bigging up the outstanding saves he does make but he certainly didn't make any at Burnley.
And no, you're right he didn't have to accept the contracts put in front of him but equally, who in their right mind turns down two contracts to make you the highest paid player in your position in the world? Particularly given the second time we did so, it was evident that no other top club in the world had any need for a goalkeeper & as such was not going to pay him even close to half what we offered him?
I'm with you on not caring what the players earn but lets not pretend De Gea is any more loyal than any other player at the club. He wanted out, he didn't get out, he signed a deal with a release clause inserted, that club went another direction so he signed a contract without a release clause but with a much, much, much higher salary. It's what most of us would probably do in his situation.
