“The way John is taking care of himself is very important,” Mourinho said of his captain, poised to start his 21st game of this campaign against Hull City. “Our training methods help. But the most important part of everything is to be happy. I once read about a famous neurologist who said: ‘We docs always say to people to exercise, eat properly, be careful with salt and protein, but we forget to tell people to be happy.’ I think John is this. He had a period here of so many doubts and question marks. Is he still the same player? Can he play at this level? Is he fit? Will he play or be in the stands? Suddenly the happiness arrives. Now look at him.”
