That is valid too. Williams is perhaps, in my opinion, just about good enough to be a ‘squad player’ in the way that Mata is a squad player - someone who gets Carabao run outs and cameos. We aren’t in that situation at left back - we have an injury prone first choice who effectively shares games with his back up. For the last two years, we have said Lingard is a squad player - but the reality is, he has pretty much player every week, and he has shown to be not good enough. So if his title is squad player, it is clear we need a better player to fill the role he has had. If Williams is going to be starting half of our games, including two cup semi finals, anytime Shaw pulls his hamstring - then we need another option to do that.
