Because changing manager won’t magically make their limited squads significantly better, and for some clubs stability is more important than committing organisational suicide on the altar of Premier League survival.
Sheffield United, Burnley and Luton will probably see survival as a bonus rather than an expectation this year, and hopping on an expensive managerial merry go round in November probably isn’t a key part of their strategies.
Trying to organise a proper press whilst one of the players won’t do any work off the ball is next to impossible, as opposing teams will break it easily.
That’s why Peps City won’t touch him, and why Liverpool wouldn’t either. Too expensive, needs special treatment and would be a tactical liability.
