One rallied his team to World Championship after a shock defeat. The other tried to a snatch goal from his fellow team mate and is a narcissistic pig. (This type argument is stupid, as you can see).

Messi has definitely spent time with better coaches, and has better playmaking abilities, showcasing he might have a better understanding of the game. On the otherhand, he appears to be playing on his instinct, which is probably very difficult to translate into words.
