Most of the claims about deterioration in Nasty's game is just make belief. He gave up a foul that led to a wonderful freekick goal. And that has caused a shitstorm. In reality though, he is actually better now, than he was last seaason. His positioning has always been very good. It is even better now. He is stronger, tougher in the tackle, and fantastic in covering up for the leftback. He is more comfortable on the ball now, and tries fewer inaccurate long balls.
That said, he will have some average games, just like he did last year. And a few poor ones too. But by and large he will be excellent, like he often is. In the game that apparently shows his "rawness and loss of confidence" he was superior to our "All World" Kompany. So if Kompany can have a poor game, and not have it ascribed to "loss of confidence" or "being a little raw," so can Nastasic. By the way Hummels have had a couple of clangers this season too. He too is an "All World" CD. Simply put, sometimes "All World" forwards and midfielders get the better of All world defenders. Talkless very good young defenders.
He tackles well, blocks well, intercepts well, is tough on jumpballs, passes well and has a cultured footballing brain. He is a very good CD. Has always been. The fallacy of his loss of form is just that, "a fallacy." Came in against Everton, and shutdown the mercurial Lukaku. Matched his movement runs and hustle all night. Does he foul a bit too much? Arguable. But so did Kompany in our title winning year. And so does Zaba now. Funny enough every Nasty foul now becomes a point for discussion. Is he commiting more fouls than he used to, yes. But this doesn't mean he is playing poorly. As a good majority of these fouls are from jumpballs. Some are really touch and go fouls. He will adjust and that will drop. This still doesn't mean he wouldn't commit fouls, he will. Like the one against Bayern, which was a good foul, in spite of the dangerous shooting position. Mueller was turning towards goal had he not pulled him.
Nasty is fine and a solid pro.
