So that's:
5 GKs (2 out on loan) - Need to look at bringing through another youngster for the development squad so as to find a new number 1 for the season after.
6 CBs (2 out on loan) - Need another one for the development squad and to bring in another top class CB which will drop one of Kaboul, Dawson, Gallas or Caulker down to 5th choice. Hope Caulker gets game time though.
3 LBs (1 out on loan) - Need at least one for the development squad. Ekotto to have Naughton as backup unless we bring a new LB in to challenge for a first team place.
4 RBs (2 out on loan) - Naughton to push Walker for a first team place. Smith and Byrne enough for development squad for now.
3 LW/M - Andros Townsend to get more game time as Bale and Pienaar find themselves rotating around the midfield spots. This may need to be reviewed! Need one more for development squad.
2 RW/M (1 out on loan) - Really need to look at bringing in a quality right winger to challenge Lennon otherwise people are getting played out of position. Need one more for development squad.
6 DMC (2 out on loan) - Healthy here with Parker, Sandro, Livermore and the return of the Hudd if needed in this position. Development squad is fine.
5 MC (2 out on loan) - Modric, Huddlestone and Livemore with one of the DMCs covering if needed. One more for development squad as Carroll gets more game time on loan.
5 AMC/CF (3 out on loan) - Well stocked in this position should we play 4-4-1-1 often. VDV backed up by Falque or even Pienaar, Bale, Modric etc... No need for any more for development squad.
4 STR (3 out on loan) - Need two quality purchases here plus one more should Defoe be sold. Kane, Lancaster and Oyenuga need to step up more on loan and decision the season after made on development squad strikers.
So promote from development squad 1x GK (squad), 1x CB (challenge first team), 1x RB/LB (challenge first team), 1x LW (squad), 1x AMC/CF (squad) - (5 players)
Sell/release first team squad players 2x GK, 3x CB, 1x RB, 1x LM/W, 1x RM/W, 1x MC, 3 STR - (12 players)
That leaves us with 22 players not out on loan (Hudd, Livemore and Naughton are covering 2 positions) and 2 U-21s in Townsend and Caulker. Squad size 20.
So buy at a minimum to challenge for a place in the first team 1x CB, 1x RW, 2x STR. Squad size 24.
