Seriously? Then name at least one moment in the game, any game at United, when he actually showed these so-called "ball playing" skills?
He is awful with the ball at his feet, i can't remember a single inventive pass from him at all. Even playing at RB, when you need your ball-skills he almost exclusively passed back, made safe passes. Then when he is in the tough situations he always hoofs it, always. Never once did i see him to actually play around the opponent.
Bailly for example does it in 50% of the cases. He is way more confident with the ball. Rojo too. And these people are not Pique or Boateng, they are just decent. But even they are miles ahead of Lindelof in terms of their ball skills.
Lindelof had a real stinker against Bristol. That was three games ago, including Everton's. So what you are on about, 8 games, what's that? Have you seen him at Bristol? Do you think that was a decent performance?
And as for other games, where is this progress exactly? I mean really. Name me a game where the swede was solid and had a good performance, deserving of a spot in United's team? For example Saints game, first of all zero of those ball-playing skills you talked about. Lindelof must have left them in the locker that day. Then was he solid at the back, well hi did not do any obvious blunders, like he had, thanks for that. But other than not making a mess i would not call his performance reassuring. For example, that moment, that great DDG save, it was Matic with Saints player, but where the hell was Lindelof, it was exactly his sport, RCB. And he was nowhere.
So his "better" performances are actually quite average ones, basically the ones where he did not screwed up. I expect better from a United's player.
