Amongst those in attendance at Old Trafford to watch Saturday's Manchester derby was Sir Alex Ferguson.
And, according to a report by The Mirror, the iconic former United manager made it a priority to seek out Pep Guardiola after the Spaniard has masterminded his team's 2-1 win.
Rather than complain about anything that had happened out on the field, however, Ferguson only wanted to offer some personal congratulations despite the defeat for his old side.
According to the report, Ferguson went as far as to "embrace and congratulate" Guardiola when they met in a corridor at Old Trafford after the game.
Considering the Scotsman's reaction to the five minutes of added time at the end of Saturday's game - he was seen shaking his head in disbelief from his seat - Guardiola may have been forgiven for fearing a watered down version of the hairdryer treatment when he saw Ferguson heading his way.
However, even with his affinity with United, Ferguson clearly couldn't help but be impressed with what the former Barcelona and Bayern Munich manager had served up in the biggest game of his Premier League career.
Some sections of Red Devils support might not be happy to hear their legendary manager fraternising with the enemy after a 2-1 defeat, but even they would have to admit that City were the superior team in the early kick off.
Although United only lost by one goal, Guardiola's team had several opportunities to extend their lead and only conceded after an error from new goalkeeper Claudio Bravo.
No matter how long Guardiola remains in English football he will never rack up the trophies Ferguson obtained during his multiple decade stint at United.
However, with a resume that includes Champions Leagues and titles in Germany and Spain, Guardiola is one of the best coaches in the modern game.
Ferguson's reaction after yesterday's derby proves that he isn't afraid to acknowledge that, even if the Spaniard is managing in the blue half of Manchester.
