The Portuguese is currently enjoying his second spell in charge at Stamford Bridge, where he's won three Premier League titles, as many League Cups, the FA Cup and the Community Shield.
The self-proclaimed Special One admits he has no intention to leave the Blues, but insists he'd be open to managing a top-flight rival if he was to leave again.
Mourinho told BBC Football Focus: "Until (Chelsea owner Roman) Abramovich tells me not to stay I don't see myself going.
"If any club comes to me now and offers me a fantastic project, offers me twice here at Chelsea, I would say no. No chance.
"The day Mr Abramovich thinks I'm not good enough for Chelsea, I want to work and if possible in England too.
"So if one day it's not Chelsea I see myself coaching another club. But I love Chelsea and I am in Mr Abramovich's hands."
