Manchester United have had a fantastic amount of legendary players throughout their history.
George Best, Bobby Charlton, Eric Cantona, Ryan Giggs, David Beckham, Wayne Rooney - just to name a few.
But, arguably, no one has gone on to have quite the impact on the world game that Cristiano Ronaldo has.
Eyebrows were raised back in 2003 when United paid £12.24 million for a teenager with one senior season under his belt but it didn't take long for them to be proven right.
Six years later, Ronaldo would leave for Real Madrid for a world-record fee, having won three Premier League titles, an FA Cup, a Champions League and becoming United's first Ballon d'Or winner for forty years.
Ronaldo has since gone on to establish himself as one of the game's all-time great, of course, but it'll forever by United and Old Trafford where he established himself.
And in a real testament to his talents, United great Ole Gunnar Solkskjaer has revealed that Sir Alex Ferguson used to grant a special privilege to Ronaldo - one that he wouldn't even give to Cantona.
"He [Ronaldo] was the only one," said Solskjear in La Gazzetta dello Sport, per AS, "who Sir Alex said: 'OK, only worry about attacking, do not think about defending.'
"Neither Giggs nor Beckham nor Cantona were ever told this."
That's quite something, considering the talents in Ferguson's squads.
Cantona, in particular, was the driving force behind United's success in the 90's but even one of the Premier League's most famous mavericks didn't get the treatment that Ronaldo got.
It's a testament to Ferguson's management, too; it took one of the most incredible players we've ever seen for him to break from his ways - and nothing short of that.
Solskjaer paid tribute to Ronaldo further, praising his work ethic and revealing that he still holds on to a memento.
"At first he was shy and didn't know the language, and then he learned it," he said. "He was in the gym forty minutes before training and he also stayed 40 minutes afterwards.
"I still have a picture of the two of us in my office."
Ronaldo clearly left quite the impression on Solskjaer - but the Norwegian certainly isn't alone there.
