Guardiola was an outspoken critic of the competition early on in the season, with the former Barcelona boss unhappy at the amound of football his players were being forced to play.
However, he now insists that he is desperate to take home the trophy for the sake of the club.
"I'd like it not for me - for the club. We are here to try to win titles," Guardiola explained.
"The first step was to arrive in the final. We did it and now will we try to win it.
"Everybody knows here in England it is so demanding.
"All around the world they play three competitions, but here four.
"It's one of the toughest schedules but if we were not interested in the competition we'd have dropped out in the first game.
"That will not happen. We will play every game to win. We deserve to be in the final and we are going to try to win.
Wigan's victory over City in the FA Cup ended Guardiola's dreams of a quadruple, but he insisted that he is not thinking about what could have been and is merely concentrated on Saunday's game.
"We are now involved in three (competitions) so we are going, of course, to win," he continued.
"The team is stable, it's been stable all season. The good moments come and there'll be another one.
"We lost. Congratulations again to Wigan but now we are going to play a final. It is a moment to enjoy and be serious.
"We know exactly against which team we are going to play and we will try to win that title.'
