I think we have a couple of players with the potential to become top class (I don't like the term 'world class') such as Coutinho (still young), Sturridge (needs to stay fit) and Sterling (very young) but we lack the players for the here and now. Gerrard s getting on a bit now too.
Personally, I think we need a dominant CB, a DM to challenge Lucas (he's our only DM), a striker and, if Suarez goes, another attacking player (able to play forward and wings) too. We could also do with getting a LB (Aly Cissokho looks to be on his way) and since Reina just about to go to Napoli, a decent back-up keeper for Migs too (Brad Jones

).
