Not at all. The position he's best in is in midfield but he's not the right man for our midfield despite how good we know he can be. He doesn't have the right supporting cast either and looks way too lightweight to play in the PL. I mean when players like Fellaini and Rooney are outperforming you in midfield, you know something's up.
So the only position we can play him is on the wing where inconsistency is an understatement. He's nothing special on the wing, basically another Nani, who on his day can be great but when it's not, is absolutely dreadful.
If it was up to me, I'd sell him while his stock is still high. In fact, I'm not entirely sure why we bought him especially since we don't really need him.
There's no point in keeping him in hope he'll regain form. There's no room for sentimentality anymore, especially when we don't need Di Maria. In fact, that's why we are where we are right now post-Fergie. Look at Chelsea, they're getting rid of Cuadrado because he just doesn't look the same player for them as he did for Fiorentina.
Not saying we have to sell him but there's nothing wrong in people wanting to do so. Not sure why it's so ridiculous when he's been so shit for large parts of he season.
