To be perfectly honest Manchester United has not  won a single game against a very notable opposition. They have been in lucky draw to be in the final. You may say Arsenal is a stong team, but they are now nowhere near Chelsea, Liverpool or Man U as shown in Premiere league.

For me Barcelona has been the team of the season. Even if you look at the points table in spanish league they not only are on top but their positive goal difference is over 70. Incredible when you think Man United goal difference is just 44 and Liveprool is 50.
