Ronaldo Nazario was an absolutely incredible footballer.
The Brazilian did some things with the ball that had never been seen before.
His influence was so great that Zlatan Ibrahimovic dubbed him the best player he had ever seen.
Zlatan told Discovery Plus, per Goal: "I always say you have the players that play the game, and the players that are the game. For me, Ronaldo is the game. When you watch him play, everyone wanted to play like him and become like him.
"The way he was moving, the way he did his stepovers, the way he did 'the snake'. The way he was moving, for me he's the greatest player through history, no doubt."
While Lionel Messi called Ronaldo the best striker he had ever seen.
"Ronaldo [Nazario] was a phenomenon, Of all the strikers I ever saw, he was the best," Messi said in an interview with AS in 2019. "He was seriously impressive."
