Mourinho said: “The character I wanted to bring to Chelsea was that of a winner.
“I wanted people to look at Chelsea and say ‘They are the best, they win things’. So far we have done well, so far we have been the best.
“Credit to Manchester United, they are doing it too this season.
“When they play well they win. And when they have problems in a game, like at Middlesbrough or Tottenham, they get a penalty and they change the game.
“We are in a battle. We cannot afford to lose and neither can they. We are enjoying it and to go on enjoying it we must keep on winning. It’s a simple philosophy.”
