Aged just 25, Messi has now been voted the world’s best player for an unprecedented fourth straight year as the outstanding talent of his generation.

I am so nervous,” a typically low-key Messi said, in Spanish, though he wore a black tuxedo jacket with a white-spotted pattern in an unexpectedly flamboyant touch. Messi’s fourth award lifted him above three-time FIFA winners Zinedine Zidane of France and Brazil’s Ronaldo. The old Ballon d’Or trophy for players in Europe was won three times by France great Michel Platini, and Netherlands forwards Johan Cruyff and Marco van Basten. Messi received 41.60 percent of the points in votes cast by national team coaches and captains plus invited journalists, who gave their top-three lists from an original slate of 23 players.
