Hate to say it but Hazard is not going to move from Ligue 1 winners and Champions League qualification to 6th place finishers in the Premier League. The best thing we can hope for is that he stays at Lille for 1 more season and we finish top 4 this coming season.
However I'll start with the centre-halves. I personally want Scott Dann, scouser, talented, very good defender. He'd also be cut price seeing as Birmingham have been relegated.
Carra/Kelly - Srktel/Dann
That means Agger and Soto would be sold. 2 defenders I absolutely love. Agger is so classy and gives us something different, when fit. But he isn't fit often enough. Soto gives his all but is a bit slow and old, can't see where he'd fit in, I'd rather see Kelly and Wilson developing.
Then there's the problematic left-back position. I'd personally sell Konchesky, Insua and Aurelio. Bring in one of Enrique/Cissokho/Izaguirre. The defence would then look like this:
Reina
Johnson - Carra - Dann - Cissokho*
The midfield is already fairly solid. Lucas and Gerrard could certainly form a fantastic partnership in the centre. I'm thinking of getting Gerrard in a deep-lying playmaker role, sort of Alonso-like. Use Lucas as a box-to-box man. Obviously however some of our midfielders need to leave and some need to come in to replace them. I have been very impressed with Meireles and Spearing personally who could certainly provide backup/rotation however the likes of Joe Cole, Poulsen and all the other garbage need to be sold, Aquilani should also leave in my opinion.
Gerrard/Meireles - Lucas/Spearing
Width is our huge problem. We have no out and out wingers. Keep Kuyt and offer Maxi a pay-cut, if not let him go. As I've said sell Joe Cole. My main targets would be Mata, Jarvis and possibly Gervinho, depending on whether Maxi leaves really. This would offer us genuine width and pace, which will help Andy Carroll start putting in consistently good performances.
Kuyt/Gervinho ------------ Mata/Jarvis
Then there's Suarez and Carroll. Sell N'gog/Jovanovic and any other **** forwards, keep Pacheco however as backup to Suarez and sign a pacey striker such as Lavezzi.
Carroll/Lavezzi - Suarez/Pacheco
This would leave us with:
Reina
Johnson - Carra - Dann - Cissokho
Gerrard - Lucas
Kuyt ------------ Mata
Carroll - Suarez
With Skrtel/Meireles/Spearing/Gervinho/Jarvis/Lavezzi and Pacheco all fighting for places.
All of this is obviously hypothetical, but would be a very nice scenario in my opinion.
