Mourinho told Chelsea's official magazine: "I think five teams will be fighting for the title.
"I put Tottenham there because they have a group of good players and I don't know why they don't belong to the fight. We are confident.
"We have a team spirit, we have a philosophy and we have a young group because only Claude Makelele is 34 so we will be ready for another big season.
"If somebody tells me over the next five years of my career I will win four championships again I will be happy.
"I can't win 10 out of 10 so I accept it. I use the words I am happy we are not happy because it means the motivation is here.
"I look forward to the next season, no problem."
