Ten years with one club is some stint in the modern era. For David de Gea, he will reflect on his milestone with Manchester United as a journey containing a number of highs and lows.
Given the magnitude of the club and its demanding fan base, there will never be a low-profile United signing, and when De Gea joined in 2011 it is fair to say the young Spaniard was thrown in the deep end by Sir Alex Ferguson.
Aged just 19 and following in the footsteps of Edwin van der Sar - the club's second greatest goalkeeper in the Premier League era, De Gea had big boots to fill.
Yet Fergie was adamant that the Spaniard had everything needed to be a United goalkeeper, a contention that was cemented after paying De Gea a visit while at Atletico Madrid.
'I can only remember Sir Alex Ferguson missing two United matches. He missed a Manchester derby in 2000 for his son's wedding. The other time? To scout the brilliant David de Gea,' United's goalkeeping coach wrote for Sportsmail.
'I was convinced that a 19-year-old De Gea was the right man to replace him. I showed a three-minute DVD compilation to Sir Alex and then we went to watch him play for Atletico Madrid at Valencia on the night United played Scunthorpe in the League Cup.
'Sir Alex knew he was the right signing inside 65 minutes. David showed composure, concentration and reflexes. He made one terrific save that went through a load of bodies.'
For De Gea, it was a dream come true to already be on the radar of one of world football's biggest clubs, and he was under no illusion with the task at hand.
'I recall reading about United's interest and I didn't believe it at first,' De Gea told Sportsmail in 2017.
'They wanted a replacement for Van der Sar, a 40-year-old who had such experience, and there was me - just a kid. We knew there would be challenges.'
And challenges there were. While a technically excellent goalkeeper, De Gea initially struggled with the physicality of the Premier League and was frequently targeted by stronger centre forwards during his debut season, leading to a handful of high-profile errors.
Ferguson dropped De Gea over the New Year and the Spaniard was sidelined for seven of the following eight league games. However, the Scot turned to De Gea for United's visit to Stamford Bridge.
Despite shipping three goals in a 3-3 draw, it was De Gea's performance against Chelsea that kickstarted his career. The Spaniard made an exceptional save to deny Juan Mata from a free kick late on to protect a point for the Red Devils.
'It (the 3-3 draw against Chelsea) might have been the defining moment of my United career. From there, it got better and better. Juan is still p***** off about that one,' De Gea reflected in our exclusive interview.
De Gea had appeared to settle between the sticks at United, until pressure was heaped back on his shoulders following an error at Spurs. The Spaniard had performed well at White Hart Lane but a lapse in concentration was punished and De Gea came in for criticism from former United star Gary Neville, who had taken up punditry duties with Sky Sports.
'Sir Alex Ferguson has had the Gerard Pique experience, who was a young player who went back to Spain [and was a success at Barcelona],' Neville said on Monday Night Football.
'I've no doubts that David De Gea can be a top goalkeeper, one of the best in the world. He's physically going to mature in the next 18 months and he needs a championship.
'If he wasn't to win the championship this year and things like this continue to happen it would be painful for him. That's where there would be problems.
'He played well yesterday [at Spurs], but playing well for 92-and-a-half minutes and then doing that in the 93rd is a problem at a club like that.'
The Spurs error was a moment where the tide turned for De Gea, who recalled how a public show of support from Ferguson in front of the Spanish press was the confidence boost he needed.
'The second big moment was midway through my second season. I had been under pressure after a game at Spurs, where Gary Neville criticised me.
'I made a mistake late on but I'd made a hatful of brilliant saves that day. It doesn't bother me. Neville was right about the error. It was snowing and I misjudged a cross.
'Not long after, we were playing at Real Madrid. Ferguson brought me into the press conference in the Bernabeu. He told everyone, the British media, the Spanish media, that I had a special talent.
'I remember what he said exactly. He compared me to a toddler taking their first steps forward. You wobble, get up, wobble, get up again and then you walk.
'Ferguson ended that press conference saying, 'The boy is walking now'. Ferguson sat next to me and told the world how much he believed in me. I felt emboldened. Ferguson was very patient with me. He did not shout and was never too harsh. He knew I needed time and trust.'
From that point, De Gea flourished. He ended the season a Premier League champion and Ferguson, who had done so much to protect and nurture his young goalkeeper, retired from football.
The Scot's departure from United has seen the club lurch from one managerial disaster to another, with David Moyes, Louis van Gaal and Jose Mourinho all trying and failing to get United back to the top of the tree.
De Gea has remained the bedrock at the heart of United's defence, head and shoulders the best player in the post-Ferguson era. From 2013 to 2018, the Spaniard was named in the PFA Team of the Year five times.
And it was midway through that spell of dominance that De Gea's head was turned by a European heavyweight. By 2015, the Spaniard was comfortably the best goalkeeper in world football and for Real Madrid, only the best will do.
De Gea appeared on the verge of returning to his home country only for a farcical admin error - in which a fax machine failed to work properly - prevented him from moving to the Bernabeu.
The episode left then-manager Van Gaal unwilling to welcome De Gea back with open arms. The stubborn Dutchman informed the press that his No 1 keeper had refused to play until the matter was resolved - a stance that De Gea denies taking - and he was dropped for the opening two games of the season.
Van Gaal turned to De Gea for United's crunch derby clash with Liverpool, a game where the Spaniard admits he was apprehensive.
'My first game back was at Old Trafford against Liverpool. Louis (Van Gaal) had said what he said. The truth is, I wasn't sure how Old Trafford would react to me,' he said.
'I was nervous walking out that day. They have always been behind me but I did wonder that day. As it transpired, they were amazing. Everyone was singing my name. It was important for me.'
With the United fans in full support of their star man, De Gea picked up from where he left off before the Madrid debacle, and was named the club's Player of the Year in back-to-back campaigns. In total, De Gea won the award four times over five seasons, indicative of the Spaniard's knack for getting United out of jail.
'Player of the Year, I would say David de Gea. Even if a goalkeeper shouldn't get Player of the Year!' Zlatan Ibrahimovic reflected in 2018.
'But he has had a fantastic year, like every other year. He continues that high level of performance, so that is my vote.'
However, the summer of 2018 saw a sea change in De Gea's trajectory. While England were dreaming of lifting the World Cup for the first time since 1966, the Spaniard endured a torrid tournament with his country.
De Gea was at fault during Spain's thrilling 3-3 draw against Portugal as Cristiano Ronaldo put three in the Spanish net, one of which wriggled past De Gea when he ought to have saved comfortably.
The United keeper was unable to save his country during a tense penalty shootout against Russia, who secured a famous last-16 victory to send the 2010 winners home in Moscow.
From there, De Gea's performances have declined. The Spaniard was left red-faced when he conceded a howler to Ismail Sarr at Watford, before Roy Keane went on a furious tirade against the keeper after poor keeping against Tottenham last June.
'I'm sick to death of this goalkeeper,' he said in a stinging rebuke. 'This is an established international goalkeeper. I'm flabbergasted. There's got to be something going on at half-time.
'Maguire and De Gea, I wouldn't let them on the bus after the match, let them get a taxi back to Manchester. De Gea is the most overrated goalkeeper I've seen in a long, long time.'
This season has seen the first signs that Ole Gunnar Solskjaer may be getting cold feet with the established No 1. The birth of De Gea's child saw Solskjaer offer back-up goalkeeper Dean Henderson a chance between the sticks, an opportunity the Englishman has seized.
The United fanbase has been torn over who should be the No 1 long term, but Solskjaer trusted De Gea for the Europa League final. However the Spaniard had a night to forget as he failed to save any of Villarreal's 11 penalties before missing his spot kick to hand Unai Emery's side the title.
Perhaps most indicative of De Gea's decline is the fact that Unai Simon has ousted him as No 1 for Spain at the Euros. The Athletic Bilbao goalkeeper has just 11 caps to his name but has won the trust of Luis Enrique over the United stopper.
'He has been fantastic David – since I have been here I have enjoyed working with him,' Solskjaer said of De Gea earlier this season.
'How long he will be able to stay at the top is just up to him because it's a pleasure to watch him being humble enough to work hard with coaches, Richard [Hartis] and Craig [Mawson], and the other goalkeepers.'
It has been a whirlwind decade for United's standout performer. Where De Gea's Old Trafford career goes from here is anyone's guess.
