De Bruyne has won five Premier League titles, two FA Cups and five League Cups at City but European success has eluded the Belgian, who came closest to lifting the elusive trophy in 2021 when City suffered a 1-0 defeat against Chelsea in the final.
"It depends who you ask (whether City's status rests on winning the Champions League). Most of the guys have been incredible anyway," De Bruyne told British media.
"Will it help? Yes. But one 90 minutes doesn't define a career. I am on around 700 games. One 90 minutes out of 700 doesn't define my career. But obviously it helps."
"We deserved to win. I am very happy and very proud," De Bruyne said. "We should enjoy the next week and hopefully we can perform the best we can... Inter are a very good team. Finals are 50-50.
"It is always difficult. You have to manage these moments. There will be moments when it is tough but in the big moments we try to do our job. Inter have great players and we have respect for them. They haven't got to the final by beating easy teams."
