Chelsea have reportedly identified Juventus midfielder Adrien Rabiot as a potential transfer target ahead of the January window.
At a time when head coach Thomas Tuchel is not short of options in the middle of the pitch, Saul Niguez has been the player to miss out on most occasions.
The Atletico Madrid loanee's lack of game time has led to suggestions that he may return to his parent club at the midway point of the campaign.
According to Calciomercato, Tuchel would take an interest in signing Rabiot should the Blues be able to part ways with Saul.
Despite making 11 appearances in Serie A and the Champions League this season, the Frenchman has not always impressed returning boss Massimiliano Allegri.
Juventus are also in a position where they are not against reducing their wage bill, with Aaron Ramsey also being tipped to depart Turin at the turn of the year.
