Can't be knee jerk here, 532 is what Shan has mostly gone with and it is what we will go with, just need to get personnel and tactics right. For the away tie, I would want as much pace and ability to carry the ball in the side as possible, with the intention to sit in and counter. I'd look at starting something like this:
Johnstone
Holgate
Dawson
Bartley
Hegazi
Gibbs
Harper
Johansen
Phillips
Gayle
Rodriguez
Bond, Mears, Adarabioyo, Brunt, Morrison, Edwards, Murphy
