Jose Mourinho once told me that managing people required a bespoke approach.
"If John Terry has a bad game, I can get in his face and shout at him and call him a f***** ******* and tell him he let everyone down; the fans, the players, the club," said Mourinho. "And I know that if I do that, I'll get the right response and he'll come back stronger. But if I talk to, say, William Gallas that way after a bad game, it will backfire. I might lose him. He might withdraw. With Gallas, I need to put my arm around him, to encourage him.
