Kempes could only speak wonders of the Argentine: "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. Before I saw more team player, now I see someone more selfish in their actions, "he added.
For the 'Matador', Messi is suffering just the opposite change than his great rival: "It's the opposite of Cristiano Ronaldo, who now plays more for the team than for himself.
But Kempes wanted to clarify that, if the '10' receives negative comments in his country, it is not precisely because of Barcelona: "I also tell you one thing, we Argentines criticize Messi because we are known to criticize what is ours. To me if they ask me with whom I would have liked to have played, I would say Messi... because I already played with Maradona".
