A die hard Chelsea fan as well.
Chelsea have very pacey wings in Robben and Duff and Barca usually attack from the middle where Chelsea's defence is strongest. Also, almost every player in the Chelsea squad can score goals, except for Kezman
But on the other hand, Eto'o is a lethal striker as well. I see a very tough and exciting tie with slight advantage to Chelsea, something like 55 to 45 for the Blues.
