Mourinho is feeling the heat following three defeats in just over a week.
"He's won titles since, but I think he's lost the plot. He believes he has become more important than the team.
"Tactically, I think he doesn't put anything in place. Apart from the players, who have changed, it's the same organisation as last season under Louis Van Gaal.
"He always blames the referee or their opponents' good fortune. There is no self-criticism."
