Juventus and Paris Saint-Germain remain in negotiations for Leandro Paredes but his arrival may depend on players leaving first, according to Bianconeri chief executive Maurizio Arrivabene.
Massimiliano Allegri has bolstered his squad during the transfer window by signing Paul Pogba, Angel Di Maria, Bremer and Filip Kostic.
Adrien Rabiot was expected to depart Turin to join Manchester United, but the midfielder's move to Old Trafford fell through.
The France international may soon be partnered in midfield by Paredes, who has been frustrated by a lack of playing minutes for PSG.
Christophe Galtier has previously acknowledged Paredes could leave after falling down the midfield pecking order, with Arrivabene confirming Juve are looking to sign the 28-year-old.
"We are talking. But, I repeat, it is very important to make the exits," Arrivabene told DAZN when pressed for an update on Paredes ahead of Saturday's 1-1 draw with Roma.
Paulo Dybala, Matthijs de Ligt, Giorgio Chiellini, Aaron Ramsey and Merih Demiral are among those to leave the Allianz Stadium this transfer window.
However, Arrivabene expects more players to depart as he looks to balance assembling a squad with Allegri and financial constraints.
"We will be happy if we manage to carry out the exits that we intend to do in such a way that the sporting result is balanced with the financial one," he added.
Juve remain unbeaten in their opening three Serie A games this season, albeit with just one win and two draws, the most recent of which coming at home to Roma.
