Pep Guardiola claims he will be regarded as a failure at Manchester City if he does not win the Champions League.
Guardiola has won five major trophies since taking charge at the Etihad Stadium in 2016, including two Premier League titles.
As yet, however, they have been unable to transfer their domestic dominance onto the European stage.
"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 return to Spurs this weekend for the first time since their defeat in last season's quarter-final first leg.
Spurs are now under the charge of Guardiola's old rival Jose Mourinho, with the Portuguese having taken over from the sacked Mauricio Pochettino last November.
Guardiola expects to face a team that shows traits of both managers in Sunday's Premier League contest.
He said: "They are quite different but there are similarities. Their teams are both quite aggressive.
"I saw Tottenham at Southampton and they were alive. They conceded a last-minute goal but I saw a team that is there.
"Every manager has different ideas, both are incredible managers. Mauricio Pochettino was there five or six years while Mourinho has been there just months, so all managers need time to make our teams play the way we want."
