Roma became the first club to win the inaugural edition of UEFA's Europa Conference League with victory over Dutch outfit Feyenoord in Tirana, Albania.
Nicolo Zaniolo's 32nd minute strike saw Roma overcome Feyenoord 1-0 to give Mourinho his first trophy since leading Manchester United to the Europa League title in 2017.
Mourinho has now won each of the five European finals he has competed in and the Portuguese is the only manager to win each of UEFA's three senior club competitions.
The 59-year-old, who is in his first season as Roma manager, has vowed to stay in the Italian capital and continue the project.
"I remain, even if some voice or offer arrives," Mourinho said. "I want to stay in Rome and we need to understand what our owners want to do in the next season because we can follow up on this story, we must define the direction for the next season.
"I feel like a Roma player, like I feel like an Inter fan, a Chelsista, I'm crazy about Real Madrid, but for all due respect for the clubs I have worked for, I feel 100 per cent Roma.
"The beautiful thing about my career beyond winning with Manchester United, winning with Porto, Inter and now with Roma is something special. Winning when everyone expects it is easy, while it is special to win when you do something truly historic. I hope the fans wait for us and celebrate with us all."
"There are so many things going on in my head right now," Mourinho continued.
"I have been in Rome for 11 months and I immediately understood where I was.
"As I told the boys, in Turin in the locker room, we did what we had to do, our job. But today it wasn't work, it was history and we wrote history. The Conference League is a competition that we thought we could win from the start, slowly becoming stronger and stronger and we met stronger and stronger teams.
"But we were aiming for it and sacrificed a few points in the league without losing qualification for the Europa League."
