Juventus coach Massimiliano Allegri says he is not concerned with the number of new players joining other Serie A teams.
The Bianconeri are yet to add new players during the winter transfer market but the Italian says no players will join unless they are quality and can be an asset for the future of his team.
"I'm not worried that other teams are signing new players," Allegri told reporters during Saturday's press conference.
"We spoke internally and everything is clear. Our squad is competitive and strong. Unfortunately we lost players because of injuries: Asamoah, Romulo and Barzagli so that's three players less.
"To strengthen the squad or to improve the depth we need quality players, who are not easy to find during the January transfer window. And that's because teams will never get rid of their best players."
Asked if striker Mario Balotelli could be an option, the 47-year-old explained: "I had [Mario] Balotelli with me where I believe he scored 14 goals.
"The problem with Mario, unfortunately, is his off-the-pitch image where everyone talks of what he does outside the game. I believe he is quality, he's technically gifted but now it's up to him to show his worth.
"As I always say, 'God helps those who help themselves'.
"So right now Balotelli has to work hard and show how good he is when on the pitch. Else he will end up being a player lost in between.
"I would like to coach him again, I like to have good players in my teams, like any other coach out there.
"But he is a Liverpool player and his job is to be important for his team."
With Juventus struggling to sign Wesley Sneijder from Galatasaray, Adnan Januzaj and Henrikh Mkhitaryan are two new names linked with the Turin club but Allegri says there are no negotiations for the two.
"They [Adnan Januzaj and Henrikh Mkhitaryan] are two very good players," Allegri explained.
"But they belong to other teams and we don't know if these teams are ready to let them go so we cannot know if they are an option for us.
"As I said earlier, we either sign quality players or else nothing, we will not sign players just to do it, knowing that they would add nothing to the squad."
