Surprised no one has mentioned Deschamps, maybe not the best, but he certainly deserves to be part of the conversation. Not many have won the world cup as a player and a manager.
Also think both Pep and Zidane are being under rated as players by some here. Pep played at a time when DMs just were not fashionable, but for what he did he was very highly rated, 6 la liga medals and a European Cup is nothing to be sniffed at, and Zidane was massively rated when he was playing, I don't get the line that he has been hyped up since, he was the most expensive player in the world for a short time when he moved from Juve to Real.
But to be fair I would agree that Cryuff probably wins this.
