It's nine years since legendary Manchester United manager Sir Alex Ferguson won his final game against local rivals Manchester City.
Fergie's team pulled off a 3-2 victory against the Premier League champions at the Etihad thanks to Robin van Persie's last-minute free kick.
And it was a season-defining moment for the Red Devils. Going into the game, they were three points clear of City at the top of the table.
That result doubled their advantage and, unlike the previous season when they blew an eight-point lead, there was no looking back.
United went on to win the Premier League title with ease, finishing 11 points ahead of City in second to give Ferguson the perfect send-off in his final season.
Here, Mirror Football takes a look at Ferguson's starting XI on that famous day in Manchester.
What is your favourite memory from the 2012-13 Premier League season? Let us know in the comments below!
David de Gea
As the only remaining member of the team, United's goalkeeper continues to wear the No.1 jersey and has since racked up 461 appearances for the club.
De Gea lifted his first Premier League honour at the end of the 2012-13 season and must have thought that was the norm at Old Trafford.
But since Ferguson's retirement, he's added just three major trophies to his collection - none of which have been the title or the Champions League.
Still only 31, De Gea could yet win plenty of prizes. Whether they'll be at Old Trafford, though, is questionable.
Rafael
Signed with twin brother Fabio in 2008, many believed the pair would follow in the footsteps of the Neville brothers and win plenty of trophies at United.
That remained a possibility prior to Ferguson's departure but, after he left, both players were soon jettisoned by subsequent managers.
Fabio left Old Trafford in January 2014 and Rafael followed suit 18 months later, beginning a five-year spell in France with Lyon.
After leaving the club in the summer of 2020, he spent a year at Turkish outfit Istanbul Basaksehir and is now playing for Botafogo in his native Brazil.
Jonny Evans
Despite impressing, Evans was never really given the chance to be of of United's first-choice centre-backs and was sold to West Brom in the summer of 2015.
The Red Devils were made to regret their decision, as the Northern Irishman has gone on to become one of the best defenders outside the so-called "Big Six".
He currently plays for Leicester, helping them win their first ever FA Cup last season.
With more than 300 Premier League appearances, a full set of club honours and 93 international caps to his name, it's fair to say Evans has enjoyed a decent career.
Rio Ferdinand
At 34, Ferdinand's career was starting to wind down in December 2012. That campaign was his last hurrah at the top, making just 14 Premier League appearances the following season.
After spending his last year as a professional at QPR, he established himself as one of the most prominent pundits in the game and has produced documentaries for the BBC.
Ferdinand is involved in many projects - including his FIVE YouTube channel, which has attracted more than 800,000 subscribers to date.
Patrice Evra
Evra was surprisingly sold to Juventus for just £1.5million in the summer of 2014 after United signed Southampton left-back Luke Shaw for £30m.
It proved to be a great bit of business by the Italian club, as he went on to win two Serie A titles and appear in a Champions League final during his two-and-a-half-year spell in Turin.
The Frenchman also continued to be a regular at international level, starting the final of Euro 2016.
Evra enjoyed brief spells at Marseille and West Ham before officially retiring from professional football in the summer of 2019.
He's gone on to make sporadic television appearances, although it's unclear whether he'll continue down that path or move into coaching.
Antonio Valencia
Valencia was a winger when Ferguson retired in May 2013, but he was turned into a right-back when Louis van Gaal arrived at the club 12 months later.
He went on to enjoy success in that role, helping United win the FA Cup, League Cup and Europa League before earning the captaincy.
Valencia left Old Trafford in the summer of 2019 and went on to enjoy spells at Ecuadorian outfit LDU Quito and Mexican side Queretaro before calling it a day in May.
Ashley Young
Like Valencia, Young was also transformed from a winger into a full-back by Van Gaal and achieved success in the role.
He went on to succeed Valencia as captain after his departure and was an integral part of the England side that reached the semi-finals of the World Cup in 2018.
United allowed Young to join Inter Milan in January 2020, where he won Serie A and reached the Europa League final before leaving 18 months later to re-join former side Aston Villa.
Michael Carrick
Carrick was another member of United's 2012-13 title-winning squad that remained at the club for many years to come.
He went on to rack up 464 appearances for the Red Devils before retiring in May 2018 and joining the coaching staff, working with Jose Mourinho and Ole Gunnar Solskjaer.
After the latter's departure, Carrick was appointed United's caretaker manager and led the team to victories against Villarreal and Arsenal, as well as a draw against Chelsea.
He said goodbye to the club earlier this month following the appointment of Ralf Rangnick.
Tom Cleverley
Cleverley lasted just one more season at Old Trafford before joining Aston Villa on loan in the summer of 2014 ahead of his contract expiration 12 months later.
An 18-month spell at Everton followed before joining Watford in January 2017, where he's remained since.
Injuries have restricted Cleverley to just over 350 club appearances to date, but he continues to show glimpses of his best - helping the Hornets beat United 4-1 last month.
Wayne Rooney
At 27, Rooney was at the top of his game when United defeated City nine years ago, scoring 27 Premier League goals the previous season.
Or that's what everyone thought. Van Persie's arrival at Old Trafford marked the beginning of the end for the iconic footballer, as his United and England career was over by 31.
That said, Rooney still went on to finish as the club's all-time leading scorer with 253 goals and achieved the same feat with England (53 goals).
After leaving Old Trafford in the summer of 2017, he spent a season with his boyhood club Everton and two years at MLS outfit DC United.
Rooney joined Derby in August 2019 and retired 17 months later when he was appointed the Championship side's manager, where he remains today.
Robin van Persie
2012-13 was arguably Van Persie's last great season, scoring 26 Premier League goals to help United clinch the title with ease.
He was expected to continue producing the goods for Ferguson's successor David Moyes but found the net just 22 times in the league during the next two years.
The Dutchman left Old Trafford in the summer 2015 for Turkish side Fenerbahce and returned to boyhood club Feyenoord in January 2018 to finish his career.
Van Persie retired in the summer of 2019 but not before adding the Dutch Cup and Dutch Super Cup to his trophy cabinet.
