We don't need anymore centre-backs if we sign Dann. We have Ayala, Wilson, Kelly as the younger prospects, as well as the experience of Agger, Carragher, Skrtel and possibly Dann. And with Robinson and Flanagan are our young prospects for the full-back positions, the defence seems to be sorted for many years to come.
However, we still need a decent LB, possibly out of:
J.Enrique - From Newcastle - £15m
A.Cissokho - From Lyon - £9m+
G.Clichy - From Arsenal - £5m+
Midfield -
R.Miereles
S.Gerrard
J.Henderson
Lucas Leiva
M.Rodriguez (Although more of a winger)
J.Spearing (Loan)
J.Shelvey (Loan)
A.Aquilani (Possibly leaving)
C.Poulsen (Possibly leaving)
J.Cole (Possibly leaving)
Aquilani should be sold around the £16m mark if he doesn't want to stay, whilst Cole and Poulsen should be sold for whatever we can get..
Even though many think we don't need anymore midfielders I still think 1-2 more would be sufficient to sustain a good challenge for the top four.
We need at least two more wingers. Mata would be perfect for the left hand side, and I would probably give Glen Johnson a shot down the right as Kelly and our new LB take the full-back positions. He has pace, dribbling ability, can get a decent cross, and even take a shot.
If we sell N'gog we will need only one more striker as Kuyt can be returned to his natural position.
