I'd go with:
Hart, Butland, Forster
Walker, Trippier, Stones, Jagielka, Shawcross, Cahill, Rose, Cresswell
Dier, Alli, Henderson, Drinkwater, Barkley, Sterling, Milner, Townsend
Kane, Vardy, Defoe, Welbeck
EDIT: Just thought of Scott Dann who more than deserves to go over Jagielka.
Speaking of starting XI's, I'd go with:
Butland
Walker, Shawcross, Dann, Rose
Dier, Henderson
Sterling, Alli, Vardy
Kane
Speed, flair, creativity and brute force with that young hunger from many to make a name for themselves, I honestly believe this side could go far if selected. Come the following World Cup, only Vardy could be at an age where it could see a decline in form seeing as speed is his greatest asset and he'll have passed the dreaded 30 mark for a footballer. Shawcross and Dann would also be around 30/31 but for CB's that's probably a prime age (just ask Football Manager

) and could still possibly feature in the Euro's in 2020. Most of the rest have at least another 2 tournaments in them after this, Butland, Alli, Dier, Sterling and Kane have about 4 maybe 5 (14,16,18,20,22?), that's a core to build around of what could be a successful England side.
Though saying that, I honestly reckon Woy will line-up with something like:
Hart
Clyne, Jagielka, Cahill, Baines
Henderson, Milner
Oxo-cube, Barkley, Lallana
Rooney
Picking this side would likely be last chances for some, Jagielka would surely not feature in the WC at 35, while Milner, Baines and Rooney would be 32/33 with younger players in their positions better than them available (that's already the case now, not that Woy would notice).
