I was mainly referring to our main players and those behind them. We can't afford to rest/swap at least three of the players you mentioned for starters in games that matter, resulting in less minutes for players that either aren't ready or those that should be long gone (Cahill & Drinkwater are two from a bunch).
Emerson can't even get into our match day squad ATM, so there has to be more than meets the eye in his regard alone.
There's obviously a drop off in quality in all squads, but our weekend midfield trio to DD, Cesc & RLC is massive.
