Hard to predict what Bilic will do, but my own preference would be wholesale changes.
Bilic could very easily make 11 changes and still put out a strong side. He could play Bond, Furlong, O'Shea, Fitzwater, Townsend, Harper, Brunt and then 3 of Pereira, Willock, Diangana and Burke, with Austin or HRK up top.
What i expect through is a 442, with HRK partnering either Austin or Burke, and then a mix of players who played saturday partnering squad players.
Hoping to see Pereira, Austin and O'Shea the most, but would be good to see Willock and Diangana as well.
