Dusan Vlahovic is expected to be ruled out for "two to three months" with an adductor injury, Juventus boss Luciano Spalletti confirmed.

The Serbia forward suffered the setback during the Bianconeri's 2-1 victory over Cagliari on Saturday.

That means Vlahovic will be unavailable on Tuesday, when Juve begin their Coppa Italia campaign against Udinese in the last 16 of the competition.

Spalletti is still awaiting an exact timeline for the number nine's absence, but the head coach says he will miss "a big part of this team".

"As far as precise timings are concerned, you have to talk to the doctors. They’re the ones who know these things," he said. "As far as I'm concerned, he will be out of action for two to three months. 

"We have to expect a few changes because we've struggled physically and mentally over the last few days. The whole group is working as best as possible and everyone deserves a spot.

"Chances come and go. Now, it's a matter of grasping them and showing how to use them. Everything is possible, but I would have preferred to have [Vlahovic] available because he’s a big part of this team.” 

Juventus are the most successful team in Coppa Italia history with 15 titles, their most recent triumph coming two seasons ago.

With victory on Tuesday, the Bianconeri will play either Atalanta or Genoa in the quarter-finals of this year's competition, and Spalletti is particularly focused on his side's style of play.

"Obviously, we have to win important games, but you have to be successful and play well, maybe even beautifully," he added. 

"Supporters have a fine palate here. Winning is not enough, you also have to play well. We will try to do both, but in the meantime, we're starting to win games. 

"For us, at the moment, they're all big tests. We want to give the supporters a better spectacle and bring good results."
