After their limp Champions League exit against Liverpool, a City collapse against Tottenham would have had the critics carping that Guardiola has no Plan B when things go wrong.
As well as demolishing some sides, Pep Guardiola's side showed it could prize open the most stubborn of opponents.
However, goals from Gabriel Jesus, Ilkay Gundogan and Raheem Sterling ensured the Etihad Stadium outfit avoid their fourth straight defeat in all competitions.

It was a familiar problem for Guardiola, who had watched United come from two goals down to beat City and deny them the title last weekend.
Gabriel Jesus opened the scoring in the 22nd minute after Vincent Kompany's long pass opened up Tottenham's defense.
Three minutes later, Spurs keeper Hugo Lloris sent Sterling flying, although replays suggested the contact was just outside the area.
In the 52nd minute, Referee Jon Moss stopped the game for a moment after Dele Alli was knocked down and needed medical attention before the game resumed in the 54th minute.
Christian Eriksen pulled a goal back for Spurs late in the first half. City's 3-1 win at Tottenham reminded the football world of what the champions in waiting were capable of, as well as keeping their hopes of breaking records alive.
Club-record signing Coutinho then delivered an outswinging corner from which Samuel Umtiti headed in Barca's second in the 51st minute, shortly after Gerard Pique had saved Umtiti's blushes by clearing a shot from Valencia forward Santi Mina off the line following a slip by the France defender.
Tottenham boss Mauricio Pochettino says there is no good time to play Manchester City despite it being a desperate 10 days for the champions-elect.
