With Manchester United present form, they could play and win anyone, Arsenal included. The fact that Arsenal had won them earlier in the premier league doesnt mean they can win them again. Manchester United has gotten so much better.
I believe Manchester United pretty much has the drive and pressure to go ahead and win any team they encounter. And now that they have got the right leadership in the form of the coach Ten Hag, its just a matter of time before the trophies come rolling in.
Manchester united have the strength to defeat arsenal, arsenal are not looking tough watching from their previous game in Premier league, with this I'm not very sure if arsenal can be firm and not allowing a defeat from Manchester United. Manchester United are strong to compete with any big team .
C'mon are you not watching the games arsenal are playing , although I won't say Manchester United are a bit stronger considering their recent wins against some tough teams like Barcelona and with the trophy they secured will just increase their morals more in winning more games but I think a match up between Manchester United and arsenal in the Europa league will be an interesting match as their second leg fixture in the premier league didn't disappoint but I think the match will be an open an open atmosphere meaning any one can take home victory.
