He was named FIFA World Player of the Year for a second time in 2003 and has continued to win trophies with Madrid as a coach, guiding them to back-to-back Champions League titles and LaLiga glory in 2016-17.
"Maybe today it's the most expensive transfer [of all time], but in two or three years." he said at Neymar's official presentation.
"I had the honour of playing with the best athlete I've ever seen in my life and I'm sure that I will never see another one like him while I'm alive".
Already, arguments have surfaced that regardless of whether he brings much-craved European success to PSG, Neymar will repay his fee off the field.
In his first public appearance as a player for the French club on Friday, Neymar said it was "sad" that people thought that his move from Barcelona had been motivated by money. There are more of them - and they will hit closer to home than Paris or Barcelona.

Neymar said he is not burdened by the price tag, which obviously raises expectations from across the footballing world.
It is all very unpleasant and ugly, but this is what our sport can come to.

At just 23, he could be the perfect heir to Messi's throne. Out of the pitch, Messi is a global star, an icon, a God to many, even. However, within the confinements of the football pitch, he is no longer a star - he is just a little kid who finds oneness with everything through football.
