Cristiano got a brace against Parma after recovering from sinusitis which kept him out of the last Coppa Italia game. Juventus did not suffer on that occasion though.
It is therefore that Sarri does not want to overuse the striker in this competition although he knows that Cristiano will not want to miss out, especially as Roma are their opponents.
"We will decide after speaking to him," Maurizio Sarri said prior to the match.
The move worked well against Udinese and he could rest Ronaldo again knowing that there are players to replace him.
