I'll give you Bridcutt and Ulloa but the others were not ever present last season or were bit part players.
You could ask why players like Lopez & Buckley have gone backwards so babdly and why a player like Conway who played 25 games for the champions looks ineffective in our side.

Unfortunately he might not have time to build an Oscar team, he needs to get this current squad working well or he will find himself out of a job or in league 1.
This is a squad that finished 4th last season and has had additional players join to replace the league 1 players that were still on...
