How does it work with what 3rd place team you play? So if England win group they then play 3D/E/F so which will it be in 3rd place in them 3 groups qualifies
Easier to explain Rocket Science.
6 potential paths left
ABDE - Group E (seems unlikely)
ACDE - Group D
ACDF - Group D (seems highly unlikely)
ACEF - Group F (seems highly unlikely)
ADEF - Group F
CDEF - Group E
The groups with sides most at peril of missing out are
B - Croatia, 2pts, negative goal difference, only a miracle saving them
C - Should England win today, the 3rd place side will have a max of 2 points
F - Czech's and Georgia both on 1pt, should they win, they're in, likewise with Georgia. However a draw for Czech (along with Georgia loss) and they could scrape through with 2 points should results in Group C go in their favour . If so, they'd be the side to face England.
I'd say England will most realistically face 3rd from D/F, but couldn't tell you how good Czech are.
I wouldn't be shocked go see ADEF be then route and England face Czech/Turkey/Georgia In Gelsenkirchen.
