Manchester united will play against big teams like Manchester City, arsenal and Barcelona. Manchester United performance is not poor, I think they are ready to play against any tesm with their form of performance.
Manchester city was not playing in europa league. You shall not go out of topic. Barcelona may be defeated by united. MU's performance is the best in EPL now. Ten haag has been using his magic to change the team to be even better and better. it seems like that he will become the new alex ferguson in MU. Mu has been preparing the best performance to face the match against barcelona.
Barcelona can be considered as a big wall that was always preventing MU since a long time ago. it's the time for MU to pass it
I think recently man united performance improved greatly, i agree that they can beat any team in the europa league but i wouldn't go as far as saying their performance is the best in the epl, barcelona game is tough because they are a moody team they can be extremily good when they want to i think it will be a competitive one.
