It is a regularly debated topic who is the best player in the world, Lionel Messi or Cristiano Ronaldo? The pair are set to come up against each other again this season in La Liga, and in the running for personal accolades such as the Ballon d'Or and the Goal.com 50. But, according to Argentine coach Alfio Basile, the Barcelona superstar is hiding something of an unfair advantage."You cannot compare anyone to Messi," Basile said. "Cristiano Ronaldo is a great human player, but Messi is a Martian."
