Simone Inzaghi has acknowledged the threat Cristiano Ronaldo will pose Lazio in the Supercoppa Italiana final, and insisted that his team needs to be "perfect" if they are to overcome familiar foes Juventus.
"He is a champion who can change the game at any time," Inzaghi said of Ronaldo at a press conference on Saturday.
"We have to be on guard, knowing that, on paper, Juve have greater potential. However, all that matters is what happens on the pitch."
Inzaghi is well aware of the size of the task for his players at the King Saud University Stadium, with it his belief that Juve will be a tougher nut to crack this time around with silverware on the line.
"We are facing a team that has a great amount of capacity, intensity, and quality. I have told my team that we must remain concentrated," he added.
"It won't be like a league game. You play for a trophy in one night. You can't make any mistakes because you have two teams that can hurt each other at any time.
"Juventus have great qualities. We will have to be very focused. In the league game, we conceded just the one goal.
"There is obviously no certainty of winning. We have confidence in our work. We face a team that has won the last eight league titles, so we will need the perfect game."
