For a manager as wonderful as Pep Guardiola and a team as metronomic as Manchester City, their recent record against bitter rivals Manchester United is somewhat disappointing.
Since moving to England in 2016, Guardiola has faced the Red Devils 15 times with his Cityzens. While a few comprehensive victories have been dished out, they have also been beaten six times by a middling United side who haven't been close to City's level in years.
Ole Gunnar Solskjaer seemed to have Guardiola's number, pulling out massive results against United's fierce rivals whenever he was under pressure in the managerial hot seat, though that wasn't enough to keep him in the Old Trafford dugout for the long term.
While it's more of a trickier prospect these days, Guardiola had enjoyed great success against United during his early years as a manager.
His first two games against the English giants came in separate Champions League finals in 2009 and 20211, both remembered for moments of genius from Lionel Messi in 2-0 and 3-1 victories.
When Pep moved to Bayern Munich, the Bavarian outfit were drawn against David Moyes' United in the 2013/14 UCL quarter finals and were given scares over both legs.
Nemanja Vidic had put United ahead at Old Trafford only for Bastian Schweinsteiger to equaliser while a Patrice Evra thunderbolt in Germany briefly had United in a position of real control. However, it would be Bayern who ran out comfortable 4-2 aggregate victors thanks to strikes from Mario Mandzukic, Thomas Muller and Arjen Robben.
When Pep made his eagerly anticipated move to England in the summer of 2016, it coincided with long-term rival Jose Mourinho's appointment across town at United, giving the football public a mouthwatering tussle between two of football's greatest ever managers.
Their first clash ended with a 2-1 victory for Guardiola, but the former midfielder was finally beaten by a United side at the sixth attempt when Juan Mata netted a 54th minute effort to win an EFL Cup tie 1-0.
Fast-forward to 2018 and we get to arguably the best game played between the two sides in modern times. City needed victory to secure the Premier League title and raced into a 2-0 lead inside 30 minutes thanks to efforts from Vincent Kompany and Ilkay Gundogan.
However, two goals in two minutes from Paul Pogba and Chris Smalling's volley secured a 3-2 win for United, ensuring City had to wait to claim their title win.
These days, it's City who reign supreme in the Premier League, and it's largely down to Guardiola's genius - and their bottomless pit of cash, of course. But his record for losing games to United is somewhat odd and unnecessary. There is no comparison between the two sides at the moment, and yet United have often found a way to strike when City seem most impenetrable.
He may have ten wins from 19 total games against United with three different clubs, but those six losses will undoubtedly bother Guardiola, and his head may explode if Ralf Rangnick's men win at the Etihad on Sunday and blow the title race wide open.
