Mourinho is happy with the way his old players have taken to his return.
"The good thing with my previous players is that what I see makes me very happy," said Mourinho. "I don't see them any different to before. When I see Terry, Cole, Lampard and the way they are working at 32, 32 and 35, it's easy for me to control the group and demand the same from the other guys.
"I can say: Look that them: they don't miss one minute; they are training like animals; they compete. So you, who are 18, 19, 21, don't tell me you can't do it."
