Chelsea boss Jose Mourinho revealed 'Billy the masseur' inspired their second-half performance in victory at Manchester City.Chelsea became the first team to do the double over City since Everton in 2010-11.
"We beat them twice but they are the best team," said Mourinho, who revealed masseur Billy McCulloch gave his team-talk in the dressing room.
"I didn't speak. It was Billy the masseur that spoke to the team. He was screaming so much in Scottish I didn't understand him but the players were clapping. It was Billy's team-talk."
"Today we won because we were the best team. We defended very well, we were very compact, we deserved it.
"A victory is a victory but a victory against a very good team is better than a victory against an ordinary team. More credit to my players.
"We love the big games. Obviously when you love it maybe you feel extra motivated for that and I keep saying, the best thing for the evolution of this team is not to play Europa League, not to be 15-20 points behind the leader but with pressure to be there, to be close to the leaders.
"(This weekend) City were the leaders. This is the best thing that can happen to this team.
"Maybe Arsenal deserve it more than us. They are top of the league and they are the favourites. We go behind them and play and watch."
