Manchester United's last ten years can be split into two - before Sir Alex Ferguson retired and afterwards.
Two Premier League titles in the first three years of the decade were followed by six years of inconsistency, change and a United side slowly slipping down the table.
Here, in the latest of a series of articles looking back over the last ten years at the club, we look at the most significant moments at Old Trafford from the game that secured Sir Alex Ferguson's final title, to the monumental decision to sack Jose Mourinho last year.
Rooney's goal vs Man City - February 2011
It was a goal that had everything. The build-up, the finish, the celebration. It also gave United a hugely important derby win that put them four points clear at the top of the Premier League - and importantly eight points clear of City to effectively end their own title challenge.
Rooney has called the goal the most important of his career, and the sheer audacity to attempt such a finish is testament to his confidence at the height of his career.
Van Persie's hat-trick - May 2013
Twelve months before Robin van Persie's ruthless first half hat-trick against Aston Villa, United had watched on at Sunderland as news of Sergio Aguero's late goal for City took the Premier League trophy out of their hands.
That moment was clearly one that motivated everyone at United, and Van Persie's arrival that summer symbolised how intent the club were on winning the title back from the Etihad.
Van Persie led the way as United did exactly that, sealing their 20th English title in brilliant style against Villa. His hat-trick will be rightly remembered for the exquisite volley from Rooney's half-way line pass, but the other two strikes were typical of his prowess in front of goal.
Ferguson's retirement speech - May 2013
It had to happen at some point, and Sir Alex Ferguson stood down as United manager at the end of the 2012/13 season following an incredible 26 years in charge.
His final message to an emotional Old Trafford was typically classy, remembering the many good times he had as United boss. But it also held advice and warnings that still apply today.
He said: "If you think about it, those last minute goals, the comebacks - even the defeats are all part of this great football club of ours. It has been an unbelievable experience for all of us, so thank you for that.
"I'd also like to remind you that when we had bad times here the club stood by me, all my staff stood by me, the players stood by me - your job now is to stand by our new manger. That is important."
To the players, he added: "The players, I wish the players every success in the future. You know how good you are, you know the jersey you are wearing, you know what it means to everyone here. Don't let yourselves down. The expectation is always there."
United have perhaps strayed from Ferguson's wishes after the ill-fated reigns of David Moyes, Louis van Gaal and Jose Mourinho since. Now, though, the concept of backing a manager through difficult periods and playing for the shirt are returning under Ole Gunnar Solskjaer.
David Moyes sacking - April 2014
"Your job now is to stand by the new manager," Ferguson told the Old Trafford crowd as he bid farewell to the club he had transformed. Eleven months later, however, and his successor David Moyes had been sacked.
Handed a six year contract, Moyes would have assumed he would be given time to build his own squad, but from the start it was clear this was a relationship that wasn't going to be a long-lasting or successful one.
What is certain is that United's ruthless decision to cut ties with Moyes so quickly set the tone for the rest of the decade. Only now, under Solskjaer, are there signs of long-term thinking not seen since Moyes put pen to paper on that six year deal.
Marcus Rashford's debut - February 2016
How different would United's recent history be had Anthony Martial not been injured in the warm-up against FC Midtjylland in the Europa League?
Initially named on the bench, Martial's injury meant Rashford was given his debut at short notice, and he never looked back. Two well-taken goals followed by two goals and an assist in the Premier League win over Arsenal three days later saw Rashford - then 18 - announce himself as United's next big thing.
He has since gone on to make almost 200 appearances, scoring over 50 goals for the club. He has four major trophies to his name, and is an England regular. At 22, he has a fine career ahead.
Van Gaal dive - February 2016
Van Gaal did an admirable job of trying to repair the damage done by the ill-fated reign of Moyes, but he will most likely be remembered for his touchline antics against Arsenal in 2016.
Unhappy with a decision given against United, Van Gaal argued with fourth official Mike Dean before throwing himself to the floor to re-enact a diving player.
Van Gaal's FA Cup win that season gave him some silverware to take from his time at Old Trafford - even if he was sacked that night - but his theatrics off the field will be most memorable to fans (especially those present at his infamous End of Season Awards night).
Rooney's 250th goal - January 2017
Rooney's place as a legend in United history was confirmed with this goal in stoppage time at Stoke. It was important in more ways than one, as it rescued United from a defeat at the Britannia, and just happened to be the strike that saw him surpass Sir Bobby Charlton's record of goals for the club.
It is a record that won't be beaten for some time, and Rooney went on to score three more times before leaving for Everton that summer. A fitting way to end an incredible spell at the club.
Europa League triumph in Stockholm - May 2017
In isolation, United's 2-0 win over Ajax to win the Europa League would have been enough to make this list as it was another European title and secured qualification back into the Champions League.
However, after the tragic events at the Manchester Arena two days before, the victory was poignant at one of Manchester's darkest points. This was a victory that showcased the very best of the club - and the city - in every sense.
Mourinho sacking - December 2018
The writing was on the wall before the 3-1 defeat at Liverpool last year, but that proved the final nail in the coffin for perennial winner Jose Mourinho, who was sacked just before Christmas.
Mourinho's appointment should have been the perfect fit at United. He knew how to win the Premier League with a squad full of big personalities, and was comfortable handling intense pressure. Maybe if Man City were not so ruthless in 2017/18, he might have brought the Premier League back to Old Trafford. But City were unstoppable and Mourinho's 'best ever season' ended with nothing.
His departure allowed Solskjaer, someone almost polar opposite to Mourinho, to come in. Form was drastically improved, and after the historic night in Paris the fan's favourite was given the job permanently. Things haven't continued as they did between Christmas and March since, but under Solskjaer United at least have a plan.
The night in Paris - March 2019
Trailing 2-0 from the first leg, United looked set for their first proper disappointment under new manager Solskjaer. Romelu Lukaku's early goal gave them hope, and Juan Bernat's leveller for PSG didn't change the task facing Solskjaer's men.
Lukaku's second after half an hour had United fans dreaming, and that became reality when Diogo Dalot's speculative effort was adjudged to have hit an arm, leaving Rashford the chance to send United through in the 94th minute from the spot. With nerves of steel, Rashford did exactly that.
What makes the comeback even more remarkable is the amount of injuries United were contending with. Ten first team options were out, including Paul Pogba, Ander Herrera, and Juan Mata. An inexperienced Scott McTominay and Andreas Pereira started, with Tahith Chong and Mason Greenwood coming off the bench.
