Guardiola has won five major trophies, including two Premier League titles since replacing Pellegrini at the Etihad Stadium in 2016.
Pep Guardiola says his reign at Manchester City will be labelled as a 'failure' if he does not win the Champions League.
The Spaniard has had a great spell at Man City so far - winning five major trophies, including two Premier League titles - since he replaced Manuel Pellegrini at the helm back in 2016.
Despite their domestic dominance, the Citizens still haven't been able to win Europe's elite trophy, and Guardiola, who has won the competition twice at Barcelona, believes European glory will define his reign at the Etihad.
He said: “We will, of course, not just be judged on the way we play but the titles we win. That is the truth. It is as simple as that.
“Last year was an extraordinary one for us but people say, ‘But you didn’t win the Champions League’.
“That is why I will be judged, if we don’t win it in my final period here, that I will be a failure here. I know that.
“But I enjoy working with my players and my players still win a lot of games. Winning a certain way is what helps you to win the titles a and we believe we can play that way. We will see at the end.”
City have not yet progressed beyond the quarter-finals under Guardiola's control.
