So just to get a jump on next year's deadweight list, assuming no one leaves in January.
Players out of contract at end of year (or, in Tarashaj's case, at end of loan):
Garbutt
Niasse
Martina
Stekelenburg
Tarashaj (2-year loan)
Players we'll for sure want rid of (all these except Tosun will be in last year of their contracts):
Besic
Bolasie
Connolly
Dowell
Pennington
Sandro
Tosun
Players we'll probably want rid of (both in last year of their contract):
Schneiderlin
Walcott
Players we might want rid of, but will probably stay (this list is highly subjective):
Calvert-Lewin
Davies
Kenny
Holgate
So that still leaves us five high-salary players that will again be hard to move:
Bolasie, Sandro, Tosun, Schneiderlin and Walcott
Contract lengths are based on half-assed research, so some are likely wrong.
