And here are those teams in text form. It’ll be interesting to see how West Ham shape up, whether they stick with the back four Moyes prefers or whether the personnel available means they have to utilise a back three.
West Ham (4-2-3-1/3-4-1-2)
Fabianski; Coufal, Zouma, Cresswell, Fredericks; Rice, Noble; Fornals, Lanzini, Benrahma; Bowen.
Subs: Areola, Masuaku, Alese, Diop, Kral, Soucek, Vlasic, Yarmolenko, Antonio.
Arsenal (4-2-3-1 probable)
Ramsdale; Tomiyasu, Holding, Gabriel, Tavares; Elneny, Xhaka; Saka, Odegaard, Martinelli; Nketiah.
Subs: Leno, Cedric, Kirk, Swanson, Lokonga, Oulad M’Hand, Smith Rowe, Pepe, Lacazette.
