From the Liverpool players in that squad the only one I disagree with is Henderson. I don't want him playing, he's been injured all season, even when he's played he was carrying an on-going injury. I want him to sit this one out and get a proper rest over the summer. He's never really been great for England either, he'll just get criticised a lot, and not just because he's had a poor game.
Of the others, Sturridge, Milner, Lallana, and Clyne are all fine, and I've had had all of them in my squad. I've posted stats elsewhere on Lallana and Milner to show why they deserve to go, because they've had great seasons (especially James Milner) and so deserve to go on merit.
I'm fine with Wilshere going. If he is fit, he can be useful. Just as long as we don't end up relying on him and needing him to hit the ground running we'll be fine.
I'm assuming if Rashford does go he'll take the place of the injured Welbeck. It might be early for him but the experience can be valuable. It's been likened to Walcott going under Sven but it could turn out to be like Michael Owen in 1998. As long as he's not rushed in and feels the pressure from media hype, and isn't damaged from the criticism you get for playing for England then he'll be fine.
Townsend is one people disagree with, and I can understand why, but like Welbeck he seems to play well for England, always seems to get a goal. Hopefully he's not in the starting XI, though.
