Asked what motivates him, Guardiola said: “Improve the team and playing better - this is the main thing. I am sad because we lost the Community Shield but especially because we don’t play as good as we can.
“The only thing I am here for is to make the team play better. I want to be on the touchline thinking I like this. Consequence is we win or lose.
“We are going to lose Premier Leagues sooner or later - nothing is eternal - not even this team that has done so much good things in the last year. We can improve.
“I am not here to say I need to win the Premier League or what will happen in other trophies.
“I know losing is part of football - more normal than winning. The important thing is stability as a club.”
