Being a coward is disgraceful at a club like United imho. As I say, I could forgive him if he was trying things and they just weren't coming off, but not even attempting anything out of his comfort zone is unforgivable. He's also developed this annoying habit of losing the ball in dangerous situations, and then standing there with a look of 'I couldn't give a feck' across his face.
Look, I used to love Val, but these past few seasons have just been so bad, in terms of performances, end product, and effort. And by effort I mean actually attempting to produce some sort of attacking threat, as opposed to just running around a lot. There are hundreds, thousands of players that would kill to play for United, and to be given game after game after game, and who would love the chance to produce. Val has all these chances, and does nothing. Doesn't even attempt to do anything.
As an example, look at that Bebe game vs Wolves. Everyone uses that as a stick to beat him with and whatnot, and yes, he was terrible. But he never gave up. He spent the whole game trying to make something happen, trying to produce a cross, trying to make a goal. Same goes with Nani when he used to try and take shots from outside the area even when he was having a stinker. And I'd far rather have players like that, players that will at least try everything, then players like Valencia that completely go into their shells and would rather do anything else then actually have to take responsibility themselves.
