Suarez for sure, but it would be close. Torres helped us to 2nd and linked up so well with the rest of the team (Gerrard & Alonso in particular), whereas Suarez can beat a team by himself, which edges it i think.
Tough call but it's got to be Suarez imo.
Remember old Trafford and the 1-4?
Torres destroyed them made that vidic chap cry
