​Argentina legend, Mario Kempes has opened up on the comparison between fellow countryman Lionel Messi and Juventus superstar Cristiano Ronaldo, claiming that, "the 31-year-old has become more selfish as time as gone by as compared to the Portugese star".

Speaking to ​Diario AS, Kempes who won the World Cup for his country in 1978. believes that Messi has become much more selfish as compared to earlier when he was more of a team player.

"Messi is Messi and Messi is Barcelona. What you do or do not do is key. When Messi is on the pitch, get ready, because you do not know when he's going to turn on you. But Messi should not surprise us. We've seen him do everything, although I think he has slowed down a bit and now I see him wanting to do more things on his own," Kempes said.

"Before I saw more team player, now I see someone more selfish in their actions. It's the opposite of Cristiano Ronaldo, who now plays more for the team than for himself."

The 31-year-old has once again had a brilliant season for the Catalan giants, scoring 51 goals in just 50 games, which helped him pick up a record sixth European Golden Shoe. However, his season ended in the worst possible way, with Valencia beating them to win the Copa del Rey on Sunday.
