Juventus are standing in the way of Chelsea completing a deal to sign Daniele Rugani after the player's agent insisted the club do not wish to sell the 23-year-old.
Reports on Friday suggested Blues officials have travelled to Italy to discuss the sale of Rugani, who is valued at £40m by the Serie A champions.
Chelsea are unwilling to match those demands but according to the player's agent Davide Torchia a bid has been lodged by the FA Cup winners.
'A very important offer has come in for Rugani from Chelsea," he told Radio Vecchia Signora.
'However, Juve don't want to do a deal and they don't want to sell the player.
'As such, just as with the [Leonardo] Bonucci situation, it seems that anything is possible.'
The saga surrounding Bonucci's proposed return to Juve could assist Chelsea in their own pursuit of Rugani.
Reports in Italy are claiming the 31-year-old centre-back is willing to accept a reduced salary to leave AC Milan just a year after moving to the San Siro and Torchia believes the deal is all-but complete.
'In our jargon, [Beppe] Marotta's words are clear. Bonucci, to me, already seems a Juventus player.
'If he reduced his wage demands it would be simpler.'
Following confirmation of Maurizio Sarri's appointment as Antonio Conte's replacement, Chelsea have made two signings in the form of Jorginho and Rob Green.
A number of deals could be completed in the final fortnight of the transfer window, with Miralem Pjanic offered to the Stamford Bridge club, while there is also interest in Gonzalo Higuain.
Whether Alvaro Morata remains at Chelsea beyond the end of next month also remains to be seen. A year on from his £58m move from Real Madrid, the Spain forward is being linked with a switch to Milan.
