Fabinho is essential. I see Henderson still as the captain and driver. Thiago is above all the others.
I envisage these 3 starting most games. I can see Fabinho not being played against the really shit teams or slow teams and playing Thiago as the deepest playmaker. I also think we might see more of the 4-2-2-2 when needed.
4 midfielders, two of Salah Mane Firmino when one needs a rest or we play tough opposition away from home
