Salah may or may not hit the same heights, expectation and/or adjusted defences, may or may not have an adverse effect. Keita will, however, create more chances than anyone who played in that spot last year. All of the front 3, and others, will benefit from that. Van Dijk is here for the full season, and will score more headers from corners than he did last season. Add to that, Shaqiri is likely to score/create more from the bench than we got from Solanke/Ings last season. Throwing in a fit Lallana, reborn Sturridge, or newly arrived Fekir, would be the cherry on the cake.
