Cristiano Ronaldo to Juventus was undoubtedly one of the biggest transfers of this era.
It was the first time that the reigning Ballon d'Or holder moved clubs since Jean-Pierre Papin joined AC Milan in 1992 - but that's only half the story.
Ronaldo is Real Madrid's all-time record goalscorer and firmly in the argument for their greatest ever player.
He was the star that the team was built around and you only need to look at their struggles this season to see the impact of his departure.
The idea that they'd sell him to Juventus was laughed off right up to the announcement as no one truly believed that such a deal could take place.
All the right people were saying that it would happen but there was always a sense that it was too much to be true.
And now, months after his move to Turin, Ronaldo's agent Jorge Mendes has revealed an interesting truth about the deal.
The 'super agent' was speaking during an awards ceremony in Italy and explained how Ronaldo asked him to work on a move to Juventus far earlier than anyone thought.
"Cristiano told me back in January that he wanted to join the Bianconeri," Mendes said, according to Tuttosport. "At that moment in time, I did not think that a deal would be possible, but I guess that I was wrong.
"I met up with [Sporting Director Fabio] Paratici and [vice-chairman Pavel] Nedved before the Juve-Real game in Turin [in April] and I then met up with [Juve President Andrea] Agnelli, too. That's when I started to believe that a deal was possible."
So Ronaldo had been planning a move to Turin for months by the time he was celebrating that incredible bicycle kick to the applause of the Juventus fans.
Even Mendes didn't think a move was possible but Ronaldo somehow did - all the while leading Real to another Champions League triumph.
You can't help but feel that there's still plenty about this move that we're yet to find out.
