If United try to rough up Barcelona in midfield like Chelsea did in the semi-final, it just won't work for them. Xavi and Andres Iniesta are just too good.
The key thing for United is a high tempo from the outset. For that reason I think Alex Ferguson will start with Ji-Sung Park in midfield and Carlos Tevez in support of the main striker.
Both those players have a tremendous work ethic and that's what you need against a side like Barca.
If Ferguson is feeling adventurous he could even start with Dimitar Berbatov, Wayne Rooney and Tevez in the same side - which would certainly raise a few eyebrows.
But United should not be scared. The mentality has to be 'we're a good side, we've got good players and we'll take you head on'.
As for Barca, Iniesta and Xavi have been their standout players this season and a joy to watch.
Iniesta in particular has impressed me. Ever since Ronaldinho left and he started to get a run in the side he's proved just how good he is. Iniesta could be some player in the Premier League.
But I still think United are favourites going into the final. They've shown real mental strength this season and you just feel like Barca have taken their eye off the ball the past couple of weeks.
Whatever happens, I'm just really happy these two teams made it to Rome. It's a dream final and one for the neutrals to relish.
A final between Chelsea and Manchester United might be good for the Premier League, but to be honest it would feel like a bit of a damp squib.
Let's just hope we get at least 90 minutes of beautiful football on Wednesday. If we're lucky we might get 120.
