City are on a 19-match unbeaten run across competitions, and look to be in pole position to win the Premier League crown this season. City fans believe Guardiola deserves to be praised for getting the club back in contention for the league title, after their not-so-great start to the season.
Fans also pointed out that the Spaniard and Ferguson have come up against each twice in the Champions League, with the former getting the better of his rival on both occasions.
During the 2011 Champions League final, Guardiola's Barcelona beat Ferguson's United 3-1, and the then-Red Devils boss was reportedly caught on camera shaking in anger.
Ferguson never managed to defeat Guardiola in his time as United manager, and admitted that 'no other team managed to dominate his side like the LaLiga giants'.
And now, City fans have taken to social media to point out why Guardiola is the better manager of the pair.
However, it didn't take long for the red side of Manchester to hit back, defending their beloved manager.
