Italian media reported that the renewal negotiations between Juventus and Paulo Dybala had reached an impasse, with the Argentine insisting on a higher salary.
The Italian giants parted ways with Cristiano Ronaldo last month, with the Portuguese superstar returning to his old club after 12 years away from Old Trafford.
Juve experienced one of the worst seasons of a decade last season, with Pirlo leading Torino's side to a place in serie A, while they were eliminated early by Porto in the Round of 16 in the Champions League.
Allegri returned to the old woman to push for the team's makeover, while star striker Dybala is seen as a key player in their future.
However, Dybala's current contract – worth £6.2 million a year – expires next summer, meaning Juve must act quickly to extend his contract or risk losing him in vain next summer.
Negotiations between Juventus and Dybala have stalled, with the two sides unable to reach an agreement on the 27-year-old's salary.
Italian media reported that Dybala agreed with the club's vision for the future and hoped to fill the gap left by Cristiano Ronaldo. However, the old woman's offer – which is understood to be lower than the offer made by the club last summer – has been rejected.
The financial woes of COVID-19 have greatly limited Juventus' flexibility in negotiations.
Dybala reportedly insisted on approaching the salary the team paid when it signed Dutchman De Ligt in 2019 (£10.3 million a year), but the club claimed it would struggle to provide a pre-champions salary level.
The Argentine is understood to be willing to commit his future to the club until 2025 or 2026, but he insists that the club will recognize his value through a lucrative contract.
The 27-year-old has scored 101 goals in 256 games and delivered 42 assists for his teammates since joining the old woman from Palermo in 2015.
