Good thing about getting someone like Salah is that it gives us options in attack but also in midfield by allowing Cout to drop back if needed. Various way of lining up and it's hard to really see any of them being weaker than the other.
Gini Can Cout
Mane Firm Salah

Gini Can Lallana
Salah Mane Cout
(Origi, Hendo, Firm back up)
Can mix things up based on the opposition and if we are dominating possession then can use first line up with Cout creating things from deep to the runners and movers up top, or if wanted to be counter attack can go 2nd with pace centrally and more solid midfield with Cout floating.
