Was Klopp not hinting the other that Gakpo plays deeper than Darwin, therefore more like Firmino, Jota & Mane did in that position - whereas Darwin wants to be on the shoulder of the last defender.
Against Chelsea, Gakpo was practically marking their DM - I guess the idea is to cut off that passing channel and try to draw out a CB and create space for the 2 wide players, Salah in particular, to run in to.
Waste of time asking Nunez to do that.
