Manchester Untied was so lucky last night. They played so damn bad, but scored three goals and all of these goals were coming from setpieces. Does Manchester United another Arsenal or what?

So many people are also paying attention to the how Manchester United very very lucky to won that game. That's unbelievable, and this is why many are starting to consider them as next Arsenal
Manchester Untied is now Arsenal's brother.
Obviously it was a luck and only against the team from under the standings, Man United conceded in the first minute that was evidence of the ugliness. But I won't think of you the same as Arsenal. Because Arsenal is actually better than MU. It's just that Arsenal lost its flagship player who is currently injured.
And looking back at the match again yesterday I have the assumption that Man United is currently very bad and even your coach is really confused to overcome this. There is no other way to improve squad performance except waiting for the new season later and Amorim must do a big overhaul.
