I'll start with the outs mentioning there value plus what they would slash off our wage bill.
Definitely
Cole FREE & 120k per week - He is not a first choice and his wages are over the amount we should be paying for a back-up, if Jose can persuade Cole to half his wages, like Terry and Lamps are going to do, to about 60k a week then he could be used as an excellent reserve. Somehow I can't see Cole taking it though.
Torres FREE & 175k per week - I really think we might have to take no fee for Torres to get a team to take on his wages. As a player he is past it anyway. Sending him to Atletico could be great if possible.
Mikel 10m & 75k per week - Despite my dislike for him, a very sought after player who could get us some much needed cash into the club. With Matic in, there is no need for Mikel and he really does not deserves to stay over Ramires or Luiz, one of whom I would drop as well.
Ramires 18m & 60k per week - Too many mistakes from the Brazilian. Between him and Luiz I would keep Sideshow Bob all day long. A mooted swap for Vidal would be excellent in my opinion.
Ba 12m & 65k per week - Not going to be the spearhead and should try to recoup as much as we can, and more whilst Ba is still able to get us some cash. Good luck to Demba
Eto'o FREE & 70k per week - If we keep any of the three we have, then it would be Eto'o as he has been good in the big home games.
The loanees (Moses, Marin, Romeu, Bertrand) 25m & 130k per week - You look at these four players, none who really have a future at Chelsea bar maybe Bertrand, but the fees and wages they cover could nearly pay for Diego Costa. That would be good business.
For me wwe would save 65m in transfers and 700k per week in wages with those deals plus the extra 100k per week from Lamps and JT lowering their wages.
There are 2 maybes for me that could leave, being Cech and Oscar, although I would keep both if possible. Courtois, Zouma and Lukaku to come back from loan leaving the squad to look like this after departures and loan returns.
GK : Courtois, Cech, Blackman
DF : Ivanovic, Kalas, Terry, Cahill, Zouma, Azpilicueta
DM: Matic, Luiz, Van Ginkel, Lampard
AM: Hazard, Oscar, Willian, Schurrle, Salah
FW: Lukaku
All I would add to this is a left-footed left back, a top class central midfielder and a clinical top class striker.
LB : Luke Shaw looks to be out of touch, with his price reaching 30m it could be out of range for a reasonable acquisition. But he could be our left back for 10 years, a gamble I would take, but if not then Alberto Moreno would be my alternative. Wages of either 80k (Shaw) or 50k (Moreno)
CM : Luka Modric would be the perfect purchase, but he looks untouchable now at Madrid. Arturo Vidal can offer a btit of everything in the middle of the park and would be the pick for me. If we could trade Ramires plus about 10m for him then we would be sorted. 120k wages
ST: Diego Costa, guy can lead a line, bring others into play. Perfect choice for us and he is suited to the Prem. 35m and wages of about 150k
Line-up would be
Courtois
Ivanovic - Cahill - Terry - Azpilicueta
Vidal - Matic
Willian - Oscar - Hazard
Costa
2nd team
Cech
Kalas - Ivanovic - Zouma - Moreno
Luiz - Van Ginkel
Salah - Lampard - Schurrle
Lukaku
