Cristiano Ronaldo has been likened to Zlatan Ibrahimovic by Massimiliano Allegri, who hailed the Juventus superstar's relentless hunger. "In terms of mentality, he is stronger than anyone else. Every day he finds personal objectives to hit and he can find them within himself," said Allegri, who won the 2011 Scudetto with Milan before joining Juve in 2014. "A player who has won everything he has at the age of 34 will find it difficult to feel hungry, but he is deadly in that sense. He has this determination that is incredible. We should all learn from Ronaldo, and I too have learned, because it's not everyone who gets to work with the best player in the world. "For example, on Saturday morning we have a game between ranks in training. He has fun, but his fun is winning the game. I explained it to him, and I've written the same about Ibra in the book, his idea of fun is winning, but I told him not everyone is like that and for some there's fun in a back-heel flick, a cheeky move, etc. And then later you bring that into the match situation. "I had Ibra at Milan, who every day would get angry about a misplaced pass and I told him that if everyone was as talented as him, there would be no problems. I told him he was the one who had to put himself at the disposal of the others, just as the best and most talented must always do with his peers."
