Lionel Messi has a natural advantage over long-time rival Cristiano Ronaldo when it comes to being the world's greatest player, according to a study undertaken by three leading English universities.

Spanish newspaper Marca reports that during a lengthy study taken on by the universities of Oxford, St. Andrews and Bristol, as well as several Australian institutions, it was concluded that left-sided players have a gene that makes them more creative and inventive when in game situations.

The discovery revealed that players who favour their left foot have inverted brain hemisphere functions, which increases their unpredictability and therefore their chances of succeeding when in tight spaces on a football pitch.

Though only proven as far as the study can be trusted, it is backed up by the fact that a host of left-sided players including Diego Maradona and Ryan Giggs have been considered up there with the best players of their generations.

Of course if true it would mean a conclusive answer to the debate that annually rages over who is better out of Lionel Messi and Cristiano Ronaldo.

Ronaldo may be a physical phenomenon, but it's Messi who is better equipped to sit on the throne if this theory is to be believed.
