I would like to see Utd win it for obvious reasons but I think that the squad is maybe one or two players short in the midfield and forward areas. Our Best XI vs Chelsea's Best XI vs Arsenal's Best XI, I would be hard pushed to pick anyone of them who I want in our first team other than what we have.
A lot of it comes down to form also. Drogba looks like a player who you could hang your hat on to score every game and the same can be said of Saha. This time last year, the pair of them were missing a lot more chances. Moreover, I think Carick will get better with time. Overall Chelsea just edge it for me atm because of their greater strength outside the first XI
