Guardiola has won five major trophies with City, including two Premier League titles, but has failed to take the club beyond the quarter-finals of the Champions League in three previous attempts.

Guardiola told Sky Sports: "I want to win the Champions League. I dream (of it) and I will enjoy preparing for the games against Madrid, to see what we can do and this process, two weeks before, will be the happiest moments of my profession, to imagine what we can do to beat them.

"If we don't beat them, OK, come the chairman or the sport director and say, 'It's not good enough, we want the Champions League, I'm going to sack you.'

"OK, (I'd say), 'Thank you, it was a pleasure'. I don't know (if this would happen). It has happened many times and could maybe happen."

Guardiola, who is very demanding in terms of the style of football his teams play, feels it is unfair to judge managers solely on the trophies they win.

He said: "We give a bad, bad message for the new generation, for our kids, to just count the winner, the trophies to win.

"You say the season is a disaster but if you win the Champions League it will be exceptional. Why? It is difficult to win it.

"If you don't, we can say in more than 100 years of history (there) were 100 failure seasons for Manchester City. That is not true.

"Always the people believe like you are Pep or Jurgen (Klopp), or another name, you have to win all the titles every season and (get) 2,000million points, (score) 2,000million goals.

"Sometimes it is not possible.

"All the times, in no sport, (has) one team won every season all the time. It's impossible."
