Maurizio Sarri reportedly faces the possibility of being sacked by Juventus should his team lose to Inter Milan on Sunday evening.
While Juventus sit at the top of the Serie A standings, the defeat at Lyon in the Champions League on Wednesday night was the club's third from seven matches in all competitions.
According to La Repubblica, the latest disappointment and his subsequent criticism of the first-team squad has put Sarri in danger of being removed from his position in the dugout.
The report claims that former boss Massimiliano Allegri, who is still under contract, is being considered as a potential replacement.
There is a suggestion that many of the senior players are struggling to put Sarri's instructions into operation, leading to the possibility of a return of a familiar face.
