Eden Hazard scored from the rebound after his initial penalty was saved by Palace goalkeeper Julian Speroni on the stroke of half-time to hand the Blues their fourth Premier League title with three games to spare.
The triumph marks Mourinho’s third top-flight title in England during his two spells in charge at Stamford Bridge.
And although the Portuguese coach was delighted to see his side clinch the title, he admitted that he is looking forward to his summer break.
“I need a rest, I’m tired,” Mourinho told BBC Sport. “It’s not easy to cope with that, but finally mathematically we are champions now. Finally we can breathe, relax and enjoy.
“We can look back and see how much we deserve to be champions. I think last season we were building something. This season there was work ethic, group ethic and principles with more stability and a few players we brought here gave us some qualities we didn’t have.”
Mourinho went on to reveal his delight at the attitude his Chelsea squad have displayed all season on their way to the title.
The former Real Madrid boss continued: “I always thought when the season started, and then winning match after match, I was feeling the team would be ready. I knew the work ethic would be there and the spirit would be there.
“The mentality in key moments in the season was there. I thought we had everything to win the title.”
Chelsea take on Liverpool, West Brom and Sunderland in their remaining games of the season.
