Manchester City haven’t taken their foot of the pedal since winning their first ever Premier League title in 2012.
Following that triumph six years ago, courtesy of Sergio Aguero’s memorable winner against Queens Park Rangers in the final game of the season, City have added two more titles to their collection.
And they’re in the hunt for another, with Pep Guardiola’s side four points behind leaders Liverpool as the second half of the 2018-19 campaign approaches.
Of course, Man City’s rise hasn’t gone down very well with their main rivals.
While the trophies have poured in at the Etihad Stadium, Man United have jumped from one disaster to the next.
Jose Mourinho’s sacking last week means the Red Devils are searching for their fourth permanent manager since Sir Alex Ferguson retired in 2013.
Once one of the most consistent clubs in the world, Man United have lost their sense of direction.
Ferdinand spots Aguero's shirt
It’s not been easy to watch for Man United’s former stars and Rio Ferdinand has opened up on the day that the power shift began.
The 40-year-old appeared on BT Sport’s What I Wore, where he discussed football shirts that mean something to him, when he spotted Aguero’s shirt from the 2011-12 season.
After talking about the pain from that final day, Ferdinand simply had to throw the Argentinian’s shirt on the floor.
“You can’t go past this, this was a bad moment man. I thought we won the league,” Ferdinand says.
“We beat Sunderland and everyone was saying ‘yeah you’ve won it, you’ve won it’.
“And then all of a sudden Sunderland’s fans went crazy.
“So I knew that they’d scored man.”
Man United fans react
Man United fans enjoyed watching Ferdinand take his anger out on the shirt.
YouTube user Shea Sealy also wrote: "Shows why Rio is a United legend."
What makes it all worse for Ferdinand is that Liverpool are now challenging Man City for the title.
Man United fans can only hope that Tottenham Hotspur, six points behind Liverpool, are able to prevent either of their rivals from becoming champions.
