The colourful Portuguese tactician has made no secret of his desire to come back to England after three successful years with Chelsea between 2004 and 2007.
He time with Inter has often been clouded by an antagonistic relationship with the Italian media and the club's fans, but after guiding the Nerazzurri to a Coppa Italia win and a Champions League final against Bayern Munich later this month, his tactical talent has won the doubters round.
And with his side also on course for another Scudetto this season, he could end the campaign with a remarkable treble.
It had been widely expected that Mourinho would leave Inter this summer and possibly return to the Premier League, while Real Madrid has been mooted as another destination, but he has declared that he might delay his English comeback.
"I lived there (in England) three years and I know I will return for sure - when nobody knows," he said.
"Will it be next season? I don't think so, but for sure I will be back in England."
He also hinted that he probably would not return to Chelsea, saying he could coach "any club. Chelsea is a beautiful team but I'm a football coach not just a Chelsea coach."
On Inter Milan's future, he remarked: "This is a team that in any case, whoever guides it, will do well.
"Are there any possibilities that I remain? Yes.
"With regards to the scudetto, we will do our duty until the end.
"As I have said many times for us the Champions League should be a dream, not an obsession."
Inter are currently top of Serie A and lead Roma, who they beat 1-0 in the Coppa Italia on Wednesday, by two points with two games left to play.
