The 50-year-old left both Porto and Inter Milan after lifting the trophy with them, but has dismissed speculation that winning it with the Spanish giants would result in the same outcome.
"I never base my decisions on whether I win or not," Mourinho told The Sun. "I work at the top level every day, thinking only about the club and never worrying about myself."
Mourinho has been linked with a return to the Premier League, with former club Chelsea and champions Manchester City tipped as potential destinations.
He guided Real to the quarter-finals of this season's Champions League with a 2-3 aggregate victory over Manchester United.
