This weekend sees the return of one of football's oldest battles, as Real Madrid take on Barcelona in the latest instalment of the "El Clasico" rivalry from the Camp Nou.
With just three points separating the sides after nine games of the new season, the tie threatens to be as competitive as ever and could well be decided by the individual brilliance of one of the stars on show.As stars go, they don't come much bigger than Cristiano Ronaldo and Lionel Messi who, between them, have won the last five iterations of the FIFA Ballon d'Or or World Player of the Year prize.
