Despite his treble triumph with Inter Milan, Maifredi believes Mourinho is overrated.
He argued: "At a technical-tactical level he has never been a great coach: he won because he always led the best teams, but he never left a trace from the point of view of the game like (Pep) Guardiola.
"As always, he will rely on the players, but I do not think he gets along with everyone: (Paul) Pogba, for example, is not on the same line. When you drive a winning team, it's easy to have players follow you until you die, but when things do not go well, the real coach has to come out.
"And he's showing himself not being this in Manchester right now."
