Not in particular no but a decent coach will drill them and play them in a way to get the very best out of them.
He's getting absolutely nothing whatsoever out of that defensive unit and he isn't changing a thing either because the same mistakes are happening, the shape is wring, the formation is wrong, the personel are wrong, the instructions are wrong, the in game management are wrong, the players are confused......I could go on and on and on and on and on and on.
He's so far out of his depth ( and I mean that genuinely ) that its truly frightening. Its clear as day as well and I cant see how anyone can have watched any of our last 10-15 games and not be alarmed by how inept He's been. It's gross mismanagement what we are currently witnessing.
People laughing their heads off as we seen the demise of Mourinho, a manager who looked like he was made of steel, ridiculed in the end because of his outdated tactics. This fella is even worse but the worrying thing is he still believes his way is the the right way.
