Check out our exclusive images of football wizard Lionel Messi sporting a new pair of gold adidas F50 adiZero football boots! Ahead of Argentina's showdown with World Cup winners Spain, Messi has switched into the gold adiZero's designed specifically for the current World Player of the Year.

**UPDATE (30/11/09)** Lionel Messi was spotted debuting a brand new colourway for the adidas F50i range during the 'El Clasico' game against Real Madrid.
