Mate the biggest criticism of him during his time at United has almost certainly been about the attacking side of his game or the complete lack there of. Come on you've seen people complain during and after games about the lack of attacking threat he provides whenever he plays haven't you?
They aren't making it up they are reacting to what they've seen in matches. The Smalling stuff is a bit different in that most of the criticism surrounding him is about his ability on the ball, which is largely subjective and blown out of all proportion by some. Almost everyone agrees he's poor on the ball though, with most of the discussion being just how detrimental that is to United's overall play.
But with Darmian you watch him regularly and you'll see he barely gets up the pitch most games. 9 times out of 10 he'll just about cross the half way line receive the ball and then pass it back and walk back to his position. And not just against the top sides, there was an FA Cup game vs Sheffield United where i was convinced he didn't enter the oppositions half.
Now i have definitely seen games where he has tried to get up and offer an outlet, a game on the left vs Palace 2 years comes to mind where he assisted and scored i think. But those games are few and far between.
Ive seen it discussed but doesn’t mean agree with any of it, because I think a lot of it is absolute rubbish, if people think he doesn’t get forward enough god knows what these people think of Valencia and Young.
In pre season he has probably already put in more decent crosses in more dangerous positions than Valencia has in the last year. When he also played on the left he was a lot more dangerous than anyone else we had other than that period.
I think a lot of what he gives us again goes unnoticed and a lot of it because “the CAF” have made up their mind on him. Yesterday for example he was good, yet I saw a lot of posts declaring him the worst player on the pitch and so on when quite frankly it wasn’t true at all.
Anyway we ain’t going to agree on it, i’m Not going to conform to the CAF opinion on him because what I see and what others clearly don’t see is vastly different. He is by no means perfect, he’s far from it, but if it’s between he and Valencia then i’d Rather keep Darmian.
Edit: hopefully Dalot solves all the issues of that position or Shaw makes LB his own so we can shift Young to the right.
