The 25-year-old arrived in the summer from French outfit Toulouse, but mainly through injury - he has been limited to just six league starts.
Now Napoli are understood to be trying to finalise a deal with Spurs to sign the French international.
Sky Italia have gone as far as to say a fee has been agreed - believed to be slightly less than the £9 million they paid Toulouse in the summer.
We've also been told Napoli Sporting Director Riccardo Bigon is expected in London on Thursday to discuss the move.
If Napoli can't do a permanent deal, then we have been told they would be happy to do a loan.
