Nothing wrong here, MU deserves the big lose 4-0 atm. It is the effect of the manager who always change his player on every match imo. He still cant find his best starting XI even though he has spent so much money. I think a good manager can build a good team with the money of Pogba. It was a big mistake to buy an overvalued player while in fact they can buy some great players to build the team.
I'm sure MU fans is so disappointed with the result and start to think "Sack Mou and bring back Sir Alex"
Although I agree with you but it was really bad as one of the favorites lost with a big score at least they should be able to score 1 goal
but in fact Manchester did not do it, we do not know what's going on is really shameful I think Mourinho should change its strategy or lineups
