Guardiola arrived in England back in the summer of 2016 when City had just beaten United to a place in the following season's Champions League, long after the reign of Sir Alex. Comparing Guardiola and Sir Alex Ferguson Manchester derby record would be quite fascinating.
While they were already beginning to inch ahead of their Manchester rivals, the former Barcelona boss soon began to create a chasm between City and United.
As United have floundered under a succession of managers, never once threatening a title challenge, Guardiola has won four Premier League crowns while playing some of the best football ever seen on these shores.
But the 51-year-old hasn't always emerged from Manchester derbies unscathed; United have scored plenty of victories over Guardiola's City, most memorably in February 2018 to deny City the opportunity to win the league against their greatest rivals.
Having won their past four Premier League games, including a 2-1 victory over Liverpool, they might fancy their chances of upsetting the applecart at the Etihad again on Sunday.
City have hardly been struggling, though, and with Erling Haaland in the team it is sure to be a game worth watching.

Regardless of what happens this weekend or on any individual result, though, Guardiola is already one of the greatest Premier League managers of all time and perhaps only second behind Sir Alex Ferguson.
City were never much of a threat under Ferguson's reign at Old Trafford, only becoming noisy neighbours in his last couple of seasons, though they often raised their game against United. All due to City and Pep Guardiola and Sir Alex Ferguson could just watch whole his team kept declining.
Under Kevin Keegan, City won the last derby at Maine Road and the first encounter at their new stadium. But, as befitting the status of the two teams during the 1990s and 2000s, United usually came out on top.
