The Blues' gritty brand of football may have upset the purists, but Mourinho revealed their millionaire owner is embracing it - literally.
Chelsea maintained their 10-point lead at the top of the Premier League by grinding out a 0-0 draw at Arsenal on Sunday.
They will land the title with a wins at Leicester tomorrow and home to Crystal Palace on Sunday.
Abramovich was at The Emirates, the third successive game he has attended where his team have stifled their opponents with mainly defensives display.
"He's very happy - I saw him hugging the players in the dressing-room after the game," said Mourinho.
"He can be in Russia and live the game the same way he lives it in a box at Stamford Bridge.
"But yes, I think he's happy and I think every Chelsea fan is happy if we win the title.
"If we win the title, we have a fantastic Premier League with everything."
In the past, Russian tycoon Abramovich has demanded sexy football, sacking a succession of managers for not producing it, including 2012 Champions League winner Roberto Di Matteo.
His top target was said to be Pep Guardiola - now at Bayern Munich - when the Spaniard was Barcelona boss from 2008-12.
Mourinho, who rejoined Chelsea after he left Real Madrid, added: "Barcelona beautiful game every week!
"When they were at their peak was when? When Real Madrid were champions? What is the beautiful game?
"For me, the beautiful game is to go to every game and know exactly the way you have to play and what you have to do.
"At Arsenal we were brilliant. Brilliant.
"A game where we were brilliant from the first minute."
Oscar will travel to Leicester and be assessed before the game after being flattened by Arsenal keeper David Ospina and taken off at half-time.
The Brazilian said yesterday: "Thanks everybody for your messages. I'm feeling much better!"
