Manchester City are in the hunt for an unprecedented treble going into the final weeks of the 2022/2023 campaign.
The champions will face Manchester United in the FA Cup final on June 3 and need one more win to claim a third straight Premier League title.
Real Madrid awaits Guardiola's side in the semi-final second leg of the UEFA Champions League at the Etihad Stadium on Wednesday.
Guardiola has won every domestic honour during his time in England but the Champions League trophy remains elusive despite some near misses in recent seasons.
Whether or not Manchester City can win the Champions League under Guardiola, the former Barcelona and Bayern Munich boss believes his tenure at the Etihad will be fondly remembered.
He said: “My legacy is already exceptional!
“(We have been) here many times already. We are not stupid, (we) know how important tomorrow is – maybe the most important since we’ve been here.
“I say to the players, live it, enjoy the moment and how fortunate we are. It’s in our hands, it depends on us.
“We don’t have to do anything exceptional – be ourselves, give everything. I have an incredible feeling about the team. Whatever happens, thank you for bringing us here again.
“The legacy is that we’ve had one hell of a time and for many years they (the fans) will remember a generation of players who for five or six years scored lots of goals and conceded very few, and that we won lots of things and won very well, and people should remember that. It would be a good book.
“Whether or not they will remember us I don’t know, but we have had a good time.”
