And Mourinho's sacking came only days before he guided Tottenham to the League Cup final against City at Wembley Stadium.
Ryan Mason, who took over from the Special One as interim manager, led Spurs at the final as Aymeric Laporte's second-half header sealed a 1-0 win for City.
Mourinho's remarkable managerial career has seen him lift major silverware during his time at Porto, Chelsea, Inter Milan, Real Madrid and Manchester United.
Speaking to TV host James Corden for The Sun, Mourinho argued that his trophy haul currently stands at "25 and a half."
According to the former Tottenham manager, the half was for the "final that I didn't play with Tottenham."
Mourinho explained: "So if you want me to be proactive now you can ask me, 'How many trophies have you won in your career?' I'll tell you 25 and a half. The half is the final that I didn't play with Tottenham.
"You ask the guys who played lots of finals and everybody will tell you, 'To play a final is a dream' and it doesn't matter if it is the first final or number 20 or number 50, a final is always a dream.
"A Wembley final is more than a dream, I played the first on the new Wembley and every time I go there, it's more than a dream and to have a chance to win a trophy with a club that doesn't have many of course was a double dream.
"I am the kind of guy that when I close the door of a club, I move and I just wish good to people, but in a funny way I would say I have 25-and-a-half titles because it's something that marks my career, which is not to play a final that I won the right to go there."
Mourinho has since signed a lucrative deal with talkSPORT as the Special One will provide his expertise at Euro 2020.
However, the ex-Chelsea head coach will return to management next season after replacing fellow Portuguese Paulo Fonseca at Roma.
