Guardiola has guided City to a 19-game unbeaten run this season and they look in pole position to win the Premier League title.
It'll be the Spaniard's third championship in England, which add to his three La Liga titles and three Bundesliga crowns with Barcelona and Bayern Munich respectively.
European football has also seen Guardiola pick up two Champions Leagues, with both final wins coming against Ferguson's Manchester United in 2009 and 2011.
Ferguson transformed United into a global superpower during his 26-year stint in the Old Trafford dugout.
He won 13 league titles and two Champions League trophies - with fans online arguing Guardiola is on his way to overtaking that record.

Anyone comparing Ferguson to guardiola need to watch the 2009 & 2011 Champions league finals. The answer is there- Andrew.mcgough (@andymcgoff) February 25, 2021
The red half of Manchester aren't taking the criticism lying down however, quickly coming to Ferguson's defence after a legendary career.
One fan said: "There's a reason Pep Guardiola chose Manchester City over Manchester United and if you don't know what that reason is then you're incredibly naïve. Sir Alex Ferguson built and rebuilt an empire year after year. Guardiola is a brilliant manager but no-one can touch Sir Alex."
Another added: "Sir Alex Ferguson would not have let Liverpool win the Premier League title last season and that is a fact but Pep did. End of discussion."
While a third simply stated: "Come back onto Twitter and the first thing I see is someone say that Sir Alex Ferguson was an overrated manager. Time to log back out again."
