The Argentinian has copped some criticism of late due to the immensely high standards he sets, but the Brazilian has come to his defence.
Given the feats that Lionel Messi has achieved in his career to date, whenever the Argentinian attacker has a slightly off game, plenty of doubters come out of the woodwork.
With Barcelona falling from grace slightly this season, the South American forward has come in for some criticism for failing to lead the side to a piece of silverware.
However, club team-mate Neymar has come to his defence, claiming that Messi is the best player that he has ever seen play the sport.
"Everyone has their own take on failure - in my opinion, Messi is the best player I've ever seen,” the ex-Santos man told TV Globo.
“I've never seen anyone like him. If I have to say anything, I will defend him to the death. He was our solution, never the problem.”
There is every chance that the South American pair could come up against each other for rival countries Argentina and Brazil at this summer’s World Cup.
Barcelona are widely expected to make significant changes in their playing personnel this summer.
