Wolves squad:
Ikeme, Lonnergan; Iorfa, Batth, Stears, Hause, CBJ, Doherty, Williamson; Coady, Saiss, Price, Edwards, Saville, Tex, Prince, Evans; Costa, Cav, Wallace; Enobakhare, Dicko, Bod, Gladon, Mason
I have left out Graham, Zyro, Silvio and John as they are long term absentees and unavailable to train. I have generously included Willo and if you add Ronan in there that is still only 26 so just enough to put on an 11v11 game in training with a few changes if necessary and that assumes all 26 are fit (which Evans, Mason, Willo and Prince aren't). That squad is about the size I would expect from a club at Championship level so I have no idea what Lambert is talking about and it sounds like utter bollocks to me. Taking 8 out of that squad reduces us to 18 which is a matchday squad.
If it's on pure numbers then we have a squad of 30 which isn't too bloated for any team at this level. If we want to change that then selling 8 isn't unreasonably too many although I would think you would have to have at least 2 coming in to balance that.
I think the 8 to leave will be: Hause (sold), CBJ, Tex (both returned), Gladon (loan), Mason, Saville, Wallace (all sold) and Evans (loan).
