With the players available I would start
Hennessy
Mepham Rodon Davies
Thomas Ampadu Allen N William
Ramsey
James Bale
I like Sorba Thomas
Good going forward and back and he keeps the ball well plus plenty of pace.
The one big advantage we have over Austria is more pace going forward but they have more technical players.
Ampadu and Allen will have to screen the back 3 well to stop Austria intricate passing.
Bale will start as we have no other focal point without Moore.
Plus Bale and Ramsey usually create chances for each other as they are on the same wavelength picking out each others runs.
