We're not sure the board is trying to do that. The usual pattern is Sarri will be given a few choices for next season, then fuck all, and the revolving door gets pushed again.
Main areas for improvement at the moment are the defence (only Rudiger gets in at the moment, the rest have been ropey on and off all season) and we clearly need a decent centre forward. Willian and Pedro will do for this season, but beyond next season we need decent replacements in several positions, but don't expect seismic movements in January.
