Chiellini played with and against plenty of all-time greats over the course of his decorated playing career, and he said when asked to pick out the best of the bunch while entering the long-running Ronaldo versus Lionel Messi GOAT debate: “Among the strongest guys I’ve played with are definitely [Gianluigi] Buffon and Ronaldo. Buffon is the best goalkeeper in the history of football, while, depending on your viewpoint, Cristiano is among the top two, three, four or five in the history of the sport. He is definitely in the pantheon of football greats.
“The toughest ones I’ve faced are Messi and Ronaldo himself. A lot of people here ask me, 'Who is better: Messi or Ronaldo?', a bit like you might with LeBron James and Michael Jordan. I don't see it as a competition, both are at the top. Obviously, out of affection, I’m closer to Cristiano, having played with him, but they’re both so strong that there can't be a one and two.”
