I think some people just have it in for him, he isn't nowhere near as bad as people make it. Salah has twisted the insides of far better defenders than him. I think if anything in that match Gabriel probably should have better getting closer, Konate did that well to help Trent against Martinelli.
Against top sides he doesn't start imo but against sides where we are going to be much more dominant then he definitely still has a role to play.
