Juventus head coach Andrea Pirlo is aware of the importance of keeping Cristiano Ronaldo fresh and says the superstar forward will decide which games he sits out.

The Portugal international scored late on in Juve's 3-0 victory over Sampdoria at the Allianz Stadium on Sunday as Pirlo's managerial reign got off to a winning start.

He had earlier hit the crossbar and came close from a couple of his other nine efforts prior to finally finding a way past Emil Audero in the 88th minute.

And with the five-time Ballon d'Or winner having recently picked up a toe injury on international duty, Pirlo is keen to closely manage his star player's fitness.

"We are thinking about it and we have talked about it together," he told Sky Sport Italia. "He is not tired at the moment because we have just started the season. But when we come up to less important games, we'll try to give him a rest. 

"He's a very intelligent lad who knows his body very well, so he is aware of when it's time to rest or step it up. When he will play depends on him."

Juve sporting director Fabio Paratici confirmed ahead of kick-off that Barcelona's Luis Suarez is no longer an option in the club's search for a new striker.

With Paulo Dybala missing the opening game through injury and Gonzalo Higuain finalising a move to Inter Miami on Friday, Pirlo is after a particular type of player to bolster his side.

"We'll give it our best. It's about finding the right balance," he said. "Quality players are always welcome, as long as they have the characteristics to bring balance to the team. But we want to use as much of our talent as possible."

Debutant midfielder Dejan Kulusevski netted the first goal of Pirlo's tenure and Leonardo Bonucci was also on target in Turin prior to Ronaldo's clinical finish late on.

Weston McKennie is another who impressed on his first appearance since joining, while Gianluca Frabotta – a surprise starter at left wing-back – also caught the eye.

"Frabotta had a good game. Alex Sandro picked up an injury, so I chose the under-23 lad who is training with us very well," Pirlo said. "I didn't consider it a risk at all to use him.

"McKennie arrived having started pre-season training in Germany, so was in better shape than some others. He made a few errors in his passing, but it was the first game, we can forgive him for that."

Pirlo has worked under some of the game's most influential coaches but vowed to do things his own way in his first managerial job.

"It will take time to get all the various ways of playing together. I don't want to just copy and paste anyone's ideas," he said. "I have my own ideas and want to adapt from the teams that inspired me.

"We haven't had much time, as the pre-season started late and then they were away for international duty. We had only one friendly too, but it was a good debut and we'll keep working on it."
