The Swiss official has voiced his admiration for the Barcelona and Real Madrid attackers, while stating the presence of high-profile coaches benefits the game
The 76-year-old feels the two are quite different on the pitch, but has nothing but positive words for both the Barcelona star and the Real Madrid attacker.
"Messi or Cristiano Ronaldo? Both! They are different but both fantastic for football," Blatter was quoted as saying by Marca.
"Cristiano wants to be the general on the pitch, lay down the law and scream here I stand. Messi, on the other hand, is like a conjurer, a magician. They are both living legends of football."
The Fifa boss then went on to stress that outspoken coaches like Jose Mourinho, Alex Ferguson, Arsene Wenger and Pep Guardiola are good for the image of the game.
"Mourinho's one of the giants in football. It's good for the sport to have big names like Mourinho, Ferguson, Wenger, Guardiola.
"Each one has his own style and charisma. They don't sit on the bench all sad and quiet."
