The Real Madrid assistant coach, who held the title of most expensive footballer on the planet when he moved from Juventus to Madrid in 2001, believes the €100 million deal for the Wales international is simply one of many "incomprehensible" fees which clubs are willing to pay in the modern game.
"Ten years ago I was bought for €75m and I said I was not worth this," the French legend for the media.
"Even now I would think that a player is not worth this. It's football, unfortunately. It is incomprehensible to pay so much. Anyway he has a great potential and he can improve alot"
