City meet Manchester United tomorrow 14 points clear at the top of the table.
Guardiola said, "That's why we're here, always we have to think we can do better. After when you win it's about the relations between all of them and how you handle the good moments.
"Listen, when you win something it doesn't mean you are going to win in the future. Always you have to be the warnings. When we won the second season, people said we'd win the next five years but we won the second one and after Liverpool won and people said they would dominate the next four, five years and a new era. Look what happened.
"Sport is a reality and the reality is tomorrow training and then the game. At the summer time, sit down with the club, take the best decisions for all of us, and start to next season. The only thing I believe completely. I don't believe at all when people say it's coming a new project for a long time. Football is what we do today, so far we are magnificent, we cannot deny it but in March nobody wins titles. I see in the team, the commitment, doesn't matter who plays everybody gives everything."
