I think Ibe will be competing most often for that spot wide right of the striker with firmino, Markovic and Origi. Lallana and coutinho will probably play left side but it's hard to say as I think it will be fluid moving up front and all of those players will probably play on both sides/through the middle throughout the course of the season.
Milner will play centrally imo, and he should do.
