So Mousset got better then got worse? I also disagree with you on Ibe, he's not improved or gone backwards, he's just been the same flakey player in all his seasons here. The Rico point is just wrong, his debut wasn't Chelsea because he was crap at Burnley the previous game - got taken off at half time, which probably would have happened today if he'd have started.
Even if you were right are we all supposed to ignore all of the players that clearly have improved under Howe? Fraser, King, Wilson, Cook, Ake, Stanislas...
You've lost your 'failed transfer policy' (TM) argument this year and are clearly grasping for an alternative.
