The England international said: "He's done well. It's not easy to follow Mourinho, but he's done it in his own way and not tried to be anything he isn't.
"He has a different style - a calm style - and he talks to the players individually. It's impressive how quickly he's got us on a winning run.
"That's credit to him and all the coaches. He hasn't tried to change too much. When players are used to something-that has proven successful, it would be wrong to change everything."
