I'm a little bit happy that he's taking the brunt of the blame for this loss because if not for the penalty, people won't understand how bad he really was tonight. We struggled immensely to move the ball up the pitch despite having 4 midfielders. Bruno was tasked with pressing much higher up the pitch and finding opportunities in those pocket of spaces, but didn't even recieve those passes. Pogba Fred and Mctominay were the ones responsible for our inability to move the ball and regain the ball in our most problematic area of the pitch. You can blame Rashford Greenwood and Bruno all you want, but at the end of the day , they were feeding off scraps, we coudn't even get the ball into midfield.
Pogba, for me, takes most of the blame as he was the extra man in midfield brought on to support Fred and Mctominay who we know aren't the best passers out from the back. He didn't do that, instead he stayed he stayed relatively high, barely ever providing any support to them. Even Bruno Greenwood and Rashford came deep to provide some support. He was also tasked with finding the right spaces in midfield to cover for our lack of width, but again his static play when we are attacking was exposed again, something that not many people seem to have picked up on. If you are not going to take up deep central positions and assume responsibility in dictating the team's tempo, he at least should have been providing himself as a passing option and width provider for our attack, again he did not do this. Anything productive he did was on the ball, and even then he was slow to release the ball.
Defensively, he and the rest of the centre midfielders, Fred and Mctominay, failed to limit arsenal playing midfield, which is why we were trapped in our half in the first half. Even with the goal, he didn't simply concede a penalty, he conceded it in an act of lazy frustration because he could not keep up with closing down arsenals attack, whilst the rest of the team were willing to do that grunt work. Some people mask his lazy play as him having an elegant running style, when in truth, its him simply being lazy. That's ok if you are a striker too, but in midfield in the premier league, you can't afford to be that laid back.
Too many excuses, too much trouble, not enough impact. He doesn't create enough near the box to be an attacker and doesn't have the determination, concentration, work rate , teamwork or concentration to play in a premeier league.
