I don’t think he is a replacement for Coutinho- think Klopp was looking at him to fill a role that has been empty for a while - the number 8 role - someone with an engine who can get up and down as well as chip in with goals and assists as well as getting stuck in.
The centre of the park has been filled with a few players who just do bits and bobs without setting the world alight but Keïta looks like someone who can add that touch of quality in the middle. Would be great to add another in there who can provide more steel then alongside Gini and Henderson will provide a balanced three.
Still think Klopp will look to replace Coutinho - he has close enough said as much in his latest interview. Both VVD and Keita arrived independent of Coutinho leaving so can see at least two players arriving for that Money but maybe in the summer
