Our 1-0 win over Chelsea on Saturday was his 221st since taking charge in the summer of 2016.
That moves him ahead of Les McDowall, who secured 220 wins during his 13-year period as City boss, with one of his campaigns spent in the second tier.
"I am so proud," Guardiola said. "The period we have been together has been magnificent.
"We can lose games, lose finals, but we play with incredible courage every single game.
"We go to play our game every single time and that makes me proud."
Guardiola’s tenure has been one of consistent success. He has won 10 trophies in his five full seasons and revolutionised the team’s playing style.
In total, his record for City reads: Played 303, won 221, drawn 37 and lost 45. In that period we have scored 738 goals and conceded 246.
Everyone at City would like to congratulate Pep on a magnificent achievement.
