Argentina legend Mario Kempes has claimed Lionel Messi will not become better than Diego Maradona even if he wins four World Cups.
Messi, who recently won the Copa America with Argentina, is widely regarded as one of the greatest footballer ever, and he has often been compared with his compatriot and footballing great Maradona.
Kempes, a FIFA World Cup winner with Argentina in 1978, believes Messi's achievements can never be compared to that of what the late Argentine legend did.
"For Messi, the misfortune is that he was the replacement for Diego Maradona," Kempes told ESPN Mexico.
"And it is very difficult to overshadow Diego, with the idolatry that he has received around the world.
"If [Messi] wants to be better than Maradona, he is not going to achieve it even if he wins four World Cups in a row.
"He still hasn't won the World Cup. No matter how many [titles he] wins or what he wins, it can never be compared to what Diego did."
Meanwhile, Messi is considered by many as the favourite to win the next Ballon d'Or after he starred for Argentina in their Copa America winning campaign.
