The Citizens remain unbeaten in the Premier League this season while they also booked their place in the FA Cup fourth round after seeing off Burnley at the weekend.
City are next in action in the Carabao Cup semi-final first-leg against Bristol City on Tuesday before they resume their UEFA Champions League campaign in the last-16 next month.
"A win helps to win more, then we are there, going to go to London to play the final," said Guardiola.
"It's important (to win trophies). To become a big club like the teams I have faced, or teams like (Manchester) United or Liverpool, with a really big history, you have to win.
"Nobody can take away what we have lifted so far - the pleasures from this team of the last three or four months, they belong to us. In the process, when you live in good moments, I say to the players, 'Enjoy it'. It is so complicated it may not happen again.
"But after, of course, to give real value to what we have done so far, what we are going to do in the future, you have to lift the titles. Without that, it's OK, it's good, but not enough."
