Neymar will become the best in the world - Eto'o

The former Barcelona and Chelsea forward has urged the Brazilian to "train, train and train" to ensure he emulates Lionel Messi and Cristiano Ronaldo

Samuel Eto'o is in no doubt that Neymar will be the best player in the world once Barcelonateam-mate Lionel Messi and Real Madrid forward Cristiano Ronaldo are past their peak.

The trio make up the shortlist for the 2015 Fifa Ballon d'Or, an accolade which the Argentine and the Portuguese have dominated for the past seven years.

Former Barcelona and Madrid forward Eto'o is confident if Neymar applies himself appropriately, he will be the sport's leading performer in the future.

"Neymar has a lot of potential. After the era of Messi and Cristiano, surely he will be number one," Eto'o, who played for Barca between 2004 and 2009, told ESPN Brasil.
