Need to start hiring better managers to begin with. Johnson was a strange choice at the time imo.I fail to see what some fans want. Players a disgrace, manager overhauls playing personnel. Form dips, need to clear out more players and change the manager. I suppose if you do this 10 times it might work once within a season over a 10 he period.
However I doubt that the whole clear out thing will happen again. The club is setting up a long term approach to recruitment, they’ll appoint a manager to fit the style opposed to appointing one that comes in and rips everything up.
