Paris Saint-Germain defender Thiago Silva believes that Barcelona's Neymar will eventually become "the greatest player in the world".

Silva has also claimed that Brazil's chances of success in the World Cup next summer will hinge on the performances of the 21-year-old.

"He can help Brazil to win the World Cup and I am in no doubt at all that he will triumph at Barcelona. I think he's really surprised the press, the way he has been playing with the team and he can bring a lot to the team's attack," he told Telefoot.

"He's a great player. I think Neymar chose the right moment to come to Europe. Here, he's going to learn a lot because he's playing with and against the best players in the world. I'm convinced that one day, he will be the greatest player in the world."

Neymar has scored 27 times in 46 games for his country.
