Carragher insisted: "Chelsea will be box office for the Premier League, for Sky, for all of us, with Mourinho there.
"They've been successful in the last few years but now I see them fighting for the title again. And if I had to tip someone now, I'd pick Chelsea. I think they will win it.
"Last year, Luis Suarez, Gareth Bale and Robin van Persie were the top three, but numbers four and five were Juan Mata and Eden Hazard. And this time they could go on to be the best players in the league.
"You've got the Mourinho factor, too. The players clearly love and adore him.
"I'd imagine they will go that extra yard for him, while Chelsea will spend, too, as they always do.
"Mourinho is just a special manager who gets special results. That could make the difference this time."
