Juventus coach Ciro Ferrara has questioned Real Madrid's signing of former Manchester United star Cristiano Ronaldo.
Juve face Real tonight in the Peace Cup and Ferrara said: "There are no perfect teams and even Real Madrid with Ronaldo it is not written anywhere that to make so much investment results will simply come.
"Juve is one of the great teams of the world and I do not see why we should ever take the field not believing we can win."
