Forget about Manchester united attack and defense, which part of their squad is working perfectly? Absolutely none. Starting from the head couch who makes irrelevant changes to their goal keeper who makes silly mistakes that usually lead to goals. The midfield is not left out too with their lack of coordination and constant losing of possessions. The attack is worse than any other position you can think of.
Manchester united is the easiest team to play against now in the premier League because they're very bad in every fundamentals. I'm fair enough to predict them finishing at position eight on the table. It is hard to tell which one is more better between Chelsea and Manchester united but Chelsea seems to be slightly better than United judging from the games played so far and statistics from each game.
I would say their offense isn't really as bad as their defense to be fair. I am not saying that it's great, but if we had to compare the two parts then I would say that we are going to see it change a lot more and it could be something that will change a lot. We should consider this to be something that will take a while and we can't really consider this to be something that's too simple neither.
United is dealing with an overall issue I can see that as well, but with a better manager I think they could be better, it's clear that they are not as bad as they should be, the team on paper looks good, but for some reason ETH makes them play terrible and the sad thing is that he denies he has anything to do with it and blames the players as well. I would fire any manager that puts the blame on players on the spot, seriously if I was a team owner and manager told the public that the players are the reason and he is innocent, I would fire him there on the press conference itself.
