The Argentine trainer feels his compatriot is without a doubt the best player around, even though he also respects the Portuguese forward and Neymar
Amato, who wore the jerseys of clubs such as Betis and Mallorca during his playing career, feels Ronaldo and Brazilian forward Neymar are great players as well, but insists they are nowhere near the 25-year-old.
"Messi is 100 times better. Cristiano is a great player, but I think that as Maradona said here in Argentina, Messi is different," Amato stated to Marca.
"As Diego also said, Neymar or Cristiano can be the best players in the world, because Messi is out of this world.
"He’s an incredible player. He doesn't touch the ball for a few minutes, then he suddenly takes two steps and scores two goals. They're different, but Lionel's far better."
Messi's netted four goals in three Liga games this term, as well as scoring twice in the Spanish Supercopa.
