Ronaldo attained the record after clinching two goals in Juventus’ Serie A 2-1 win over Lazio on Monday night.
The 5 Ballon d’or winner scored twice in the space of three minutes in the second-half to give Sarri’s men all three points against Lazio.
“When Cristiano smells blood, He is extraordinary, as he recovers so quickly between games,” Sarri told Sky Sport Italia after the game.
“He is not just physical but also psychological.
“He could be someone who uses up so much energy in each game, but he recovers it every time, and he is world-class in mind as well as the legs.” Sarri said.
