Sunderland still do not have an agreement with Caen for the signature of striker Alexandre Mendy this summer, according to Sky Sports News.
The Black Cats are in the market for a forward and the club have been pushing hard to land one of their top targets.
Mendy is a key target for the club and the striker recently spoke about his enthusiasm at the prospect of joining Sunderland.
There was talk of a deal being imminent for the 30-year-old striker to move to the Stadium of Light this summer, with suggestions he has been on Wearside.
However, it has been claimed that Sunderland still have work to do in their pursuit of the striker in the ongoing transfer window.
While Mendy is keen on the move, the negotiations between Sunderland and Caen have not been as straightforward as they expected to be.
The French club are prepared to let Mendy leave, but only for a price they consider to be fair.
For the moment, there is still no agreement between the two clubs for the striker to join Sunderland.
The Black Cats are still pushing to sign him but there is still work to do to get a deal over the line.
