Allegri confirmed that Ronaldo, signed from Real Madrid for 105 million euros in the close season, will be managed in the same manner as Zinedine Zidane previously did - with tremendous effect.
At the age of 33, the Italian feels the five-time Ballon d'Or winner should get to grips that he will need to conserve energy to remain at the elite level he's displayed over the last decade.
"He has to understand that there will be times when he starts on the bench and then just plays half an hour," Allegri said in a recent press conference, as quoted by EuroSport.
"Even he will need a break at some point. At Real Madrid, he was excellently managed."
He added: "Ronaldo trains very competitively, he takes nothing for granted and is a champion, building his own success over the years through hard work and sacrifice.
"He is a great example for the younger players and he raises our overall quality... Ronaldo is bringing a great enthusiasm to Italian football."
