I think that it's not so much just about January in and outs but also what we need to do in the summer as well. Making wholesale changes in a single window is never normally advisable, but if we are serious about being in the Premier League next season I think we need to be looking for about 7 or 8 players, spread over the next two windows. These need to be better than those we already have (not bench warmers).
Goalkeeper - KD + another. Offload Bart, not a knee jurk to today's shocker, but generally I don't think he has been that convincing when he has filled in for KD.
Left back - Harding + Fox - Offload Dickson
Right Back - Richardson + another. Offload Butterfield
Centre Back - Left footed centre back - Jos + another - offload Jaidi and Seaborne. Right footed centre back - Fonte + another. Retain, but Loan out Martin.
Right wing - Chappers + De Ridder - offload Puncheon
Centre Midfield - Cork, Spiderman and Hammond + another
Left Wing - Lallana + another - offload Holmes
Centre Forward - Lambert, Guly + another. We need to see how Barnard performs in the 2nd half of the season, if he doesn't cut it then we will need to replace him as well - offload Connolly.
Key positions that we need to sort ASAP are an additional striker with height and pace, a left winger (with pace), so that we have the option of playing Lallana in the hole behind the main striker. Anoher left footed centre back - we are screwed if Jos gets injured until such time as Jaidi and Seaborne are fit (which doesn't look like being anytime soon).
