Patrick Vieira believes that France midfielder Paul Pogba has room for improvement before being considered one of the world's best.
The 21-year-old Juventus star is expected to start for Les Bleus at the World Cup after an impressive campaign in Serie A.
"He still has to improve certain sectors of his game," Vieira, who lifted FIFA's showpiece trophy himself with France as a player, is quoted as saying by ESPN. "At his age, he's an extraordinary player with enormous potential.
"I know him personally and I like him a lot because he has his head on his shoulders. He is going to become a great player for the French national team and also on the world stage."
Pogba has featured 11 times for France since making his debut in 2013.
