Cristiano Ronaldo "proved his worth" in Juventus' 2-1 win over Inter on Tuesday, according to head coach Andrea Pirlo.
Ronaldo was rested for Juve's previous Coppa Italia win – against SPAL last month – but netted a brace in the first leg of the semi-final victory over Inter at San Siro.
The Portuguese star has scored the most braces of players in Europe's top five leagues with eight in all competitions this season.
Pirlo praised Ronaldo, who was replaced by Alvaro Morata with 13 minutes remaining.
"He played an excellent match and proved his worth," Pirlo said.
On substituting Ronaldo, Pirlo added: "He is playing a lot and we have many matches very close to each other.
"Saturday we will have a very important one against Roma, so I thought it would be good for him to rest and recover some energies."
Ronaldo's double came after Lautaro Martinez had opened the scoring for Inter, who beat Juve in Serie A action last month.
Pirlo, whose team won the Supercoppa Italiana against Napoli in January, said his side learned from the league outing against Inter.
"We weren't in the championship match, but it served us as a lesson, because we gathered together and the victory in the Supercoppa made us realise we can compete for every objective. We haven't done anything yet, we just won the first leg," he said.
"We have prepared the game well and if we are focused and have the right attitude it becomes hard for everyone, even though we know that it is not easy to maintain this pace by playing every three days.
"However, the squad is large and there is no problem in alternating players. In the second half we lowered ourselves a bit, also thanks to Inter, but it's normal in the 90 minutes."
Before next week's semi-final second leg, Juve host Roma in Serie A on Saturday.
