"For me, there are three players who are better than the rest: Iniesta, Ronaldo and Messi," he added.
"But, the best is Messi. There is nobody who can do the things he does."And Neymar was also quick to acknowledge recent declarations from Messi, who branded his felllow Ballon d'Or nominee an "excellent footballer".
"Can you imagine the best in your profession giving you praise? It made me very happy and I can only thank him for his words," he concluded.
