#1 Lionel Messi (FC Barcelona)
The genius that is Leo Messi does not warrant any other place in this list than the numero uno position.
Be it his injury-time winner in a 3-2 winner at the Bernabeu last season or his stunning brace in the 2011/12 Champions League semifinal, Messi has dominated this fixture, unlike any other player.
Scoring a massive 25 goals in 37 Clasicos, Lionel Messi is undoubtedly the greatest player that has ever taken part in this feisty affair.
The man has single-handedly taken Barcelona to victory against Real Madrid at times and has also created chances on a plate for his teammates.
Messi is expected to reach the unheralded figure of 30 Clasico goals before he hangs his boots up - a feat which will be one of his biggest and most credible achievement.
