Mourinho, who was unable to guide Chelsea to any silverware last season, remains unperturbed by claims that the West London club must win the title if they are to be considered a success.
He told reporters: "At the end of the season, you, the supporters and the players will judge my work. More important than all of you, my boss, my owner, my board - they will judge my work too.
"For some to achieve success will be to win the league. I understand that because of my last 10 years and Chelsea's last 10 years.
"But I really don't care about it, all I care about is being myself - working hard every day, having ambition to win always the next game."
Chelsea face Burnley on Monday at Turf Moor in their opening game of the Premier League season.
