Put it this way, all the following being fit; Winks, Dembele, Wanyama and Dier then Barkley would have been 5th choice for me. It’s only because there’s a ridiculous amount of injuries in one position that we look light (you can argue the fitness of Dembele and Wanyama now, but 18 months ago when Barkley was being touted ?...).
Grealish I’d rank lower than Barkley for CM and if you put him as AM then he’d be behind Eriksen, Dele, Son, Lamela and Moura for the AM roll, so 6th choice in a position we play at the most 3 players. Sigurdson similarly.
I guess Poch had a similar opinion about these players ability as I do and thought the likelihood of needing a 5th choice CM and 6th choice AM to play regularly was limited and that in the event of a crisis the youth could cover 1/2 games. Bare in mind we’ve had to leave some players out of the CL squad as it stands already. If we get rid of the GKN, Jansen, Vorm and any other dead weight then we can bulk the squad out again.
That’s just my take on it.
