Wilshere has played well for England when they've needed him to though, he scored twice and was MOTM against Slovenia I think? Roy trusts him, the same with Welbeck. He's had an average season with little playing time but would have gone if fit. I can tolerate a manager having a few favourites, although I think Roy goes a little too far with that. Stones, Delph, Milner, Wilshere, Henderson, Rooney and Sturridge will probably be counting themselves somewhat lucky. They've collectively struggled for game time and/or form this season.
I think the West Ham squad will feel a little hard done by. Carroll, Antonio, Cresswell and Noble could all make reasonable cases in different ways. Simpson, Albrighton and Defoe too.
