I'd go for this (which is what I suspect that we will see):
Johnstone
Furlong
Ajayi
Bartley
Townsend
Livermore
Sawyers
Phillips
Pereira
Diangana
Robson-Kanu
Bond, Hegazi, Brunt, Krovinovic, Edwards, Zohore, Austin
Regards Bilic having the preference for a lopsided back 4 with one of the full backs being allowed to bomb on more than the other, whilst Furlong has done well attacking this season, he is quite good in the air and is a solid defensive option at the back post. He began his career as a centre back so although he might be good going forward, he can do a job tucking in better than Townsend could in my opinion.
