First time I saw Ronaldo, he was playing against supposedly the best right back in England at the time, and he made an idiot of him over and over throughout the game. It's possibly that game that cost us a chance at signing Ronaldo because the United players begged Sir Alex to sign him after that. Ronaldo had recently visited Arsenal to explore moving to us. After that game, it was over. Sir Alex took out the checkbook.
I don't really have a first memory of Messi. He was just sort of there.
