Get rid of Keane and buy Thierry Henry - he's brilliant up front with Torres (who, for some reason, sees no point in learning how to go round the keeper or beat the offside trap!). I give Henry complete creative freedom and a free role and he scores at least one goal every game (16 in 12). Fixes the lack of a potent free kick taker too (why are Gerrard's free kick stats so low?).
I'd always keep Babel - he continually scores edge of the box screamers after running in from the left wing - the fans love him! And Kuyt ... he's fantastic on the right for me. gets in a lot of crosses and creates goals.
