He needs to get Grealish back into a more central position where he can influence the game more. Not sure if Abraham will be fit, so Kodjia will play centrally if he doesn't make it. Presuming all are fit, I would go with:
Nyland
Elmohamady Chester Tuanzebe Hutton
Jedinak
Grealish McGinn
El Ghazi Abraham Bolasie
Subs - Moreira, Bree, Taylor, Bjarnason, Hourihane, Adomah, Kodjia
