All of our defenders have made mistakes this season. It goes with the territory. Foyth's the only one who's got kicked to the curb though. As you say, the sky's the limit but I fully expect Mourinho to bin himSky is the limit for this kid. Can hardly remember to see a defender being that ridiculously good and bad at the same time.
A bit more muscle and if he can just clean up his game a bit, not so much that he loses that uniqueness, but just enough so that he can manage on a regular basis in the PL. Like a younger Luiz. Yes, there will be mistakes, but the overall cost/benefit is still positive.
Imagine Foyth passing the ball to N'Dombele? It would be impossible to play the high press against us then.
And of course. Love the comments. Right attitude - whatever happens.
