Loads of incorrect points but main one, Wirtz and Hugo's job is to align with an existing team when they join as new joiners and not other way around.
If you bother to watch some of the post game analysis, there was one where they pointed how many times Salah wasn't getting the ball on his side and was constantly going down the left, it was all too predictable about Mo's faults.
Ok so let's go with your view, and start Salah on the bench. Who would you play instead up front with what we have now currently?
