One thing is for sure, after about 5 games into the season we all know better about selecting who we want playing. As for now I would select this:
Back four with Pickford of course, Martina as I think Kenny is not ready yet... for physical Stoke I mean... but maybe it would do him good to start right away but it could do him harm. Baines, Keane and Jagielka.
Klaessen, Gueye, Barry, (or Davies, Schneiderlin, Sigurdsson)
Lookman, Rooney, Sandro.
