Young, talented, Argentine.... the new Maradona? ...naah don't put the pressure on the boy, let him be himself.

Who's the boy you heard his name when he was only 13?
Who's the boy who scared the hell out of Florentino Perez?
Who's the boy who Maradona wants him to wear number 10 jersey of Argentina?
Who's the boy who, at the age of 18, completely outclassed Roberto Carlos and Zidane in hs first El Clasico match?

the answers to all questions are Lionel Messi.
