It's a bit of a problem when your major problem areas are at centre back, full back, centre midfield, on the wings and also up front.
In terms of Keane and defence in general, I assume both Williams (I say 50/50) and Jagielka (100%) are gone in the summer. Martina you'd think would be booted out due to us having Kenny and Coleman for RB and his inability to play left back or anywhere else to anything other than Sunday league standard. Mori is a bit of a hit and hope but I actually feel he may come good for us in time. Whether he wants to stay or not is probably the question. I'd not be surprised to see him go in the summer, hence thinking Williams may stay another year. Jagielka, Mori and Martina going leaves Coleman and Kenny at RB, Holgate, Williams and Keane at CB and Baines at LB. This is a huge worry because only Holgate is half decent for us at CB, while the other two are complete garbage. But will we really sign two new starting centre backs? We need it, but it won't happen. Baines needs to be back up. A top quality left back simply must be brought in ASAP.
Next season defence should be Coleman + three new signings, but I feel it will probably be Coleman, Williams, a new centre back plus Baines. If that happens we're well and truly going down.
