You can't get over Alli's punchable face so you pick Ince? I think that's called cognitive dissonance .
Alli and Dier could each do a job for England, but you'd have to build a team that works as a team. It's the age-old problem - do you pick the eleven best players or do you look at who's available and craft a style that fits as many as possible? Either way, the press and some fans will be pissed off.
I've said this before - Alli has been effective for us because he's been given a fair bit of freedom. Even so, many Spurs fans are frustrated with him and wouldn't actually have him in their first team. I would, because you can afford one player who just runs about a lot and pops up with crucial goals and assists. You just have to recognize that he's still a kid. He's incredibly fit, pretty strong, and skilful; just inconsistent - gives the ball away a lot, flits in and out of the game a bit.
Dier has surprised all of us - we were desperate for a DM in the Summer and Poch/Levy got a lot of stick for us ending up with Dier. He really has been a revelation...but the proviso is that he's got a fairly simple job. He's asked to sit in front of the defence for the most part, then when we get the ball he drops back to let the full-backs push on. He's bloody good at that job. If you ask him to do that for England then fair enough, and he's going to look pretty good. If you ask him to do anything else in midfield then you're asking for trouble. One big point in his favour when you're looking at a tournament is that he can do a job at DM, CB and RB.
