No doubt that Lionel Messi is the best

Xavi: "For me, there is no heir to Messi. There will never be one. There will be very good footballers, but nobody at Messi's level"
"Though now they try to sell the story of the Cristiano and Messi battle, those of us who know football, know there is no comparison."
"When Messi ends his career, there will be Neymar, Hazard, five or ten players at a similar level, but none with the unquestionable superiority of Messi."
