Watford are in talks with Tottenham over the permanent signing of Moussa Sissoko.
All parties are confident a move for the midfielder can be completed before the transfer window closes on Tuesday.
The 32-year-old joined Spurs from Newcastle on Deadline Day in August 2016 and has gone on to make over 200 appearances for the north London club.

However, Sissoko appears to be out of favour under new Spurs head coach Nuno Espirito Santo, who has left him out of three of the four squads he has named so far this season.
Watford's move for Sissoko comes as his fellow midfielder Will Hughes looks to be heading for the exit at Vicarage Road.
Crystal Palace have agreed a deal worth £10m - with £6m paid up front - for the 26-year-old, who is set to undergo a medical with the Eagles on Friday.
Hughes has entered the final year of his contract and turned down Watford's offers to renew his deal, resulting in him being made to train with their U23 side.
Burnley were also interested in Hughes, who has not played any first-team football this season.
After agreeing the deal to sign Hughes, Palace are now set to turn their attentions towards signing a striker, with the search likely to go down to Deadline Day.
Lille could move for Spurs' Aurier
Lille will consider a move for Tottenham's Serge Aurier if they lose right-back Zeki Celik.
Celik has been a target for Fiorentina but the Italian club are now closing in on the signing of Alvaro Odriozola from Real Madrid, according to Sky in Italy.
Celik has been of interest to other clubs, however, and Lille has been presented as a potential option to Aurier, who wants to leave Spurs.
Spurs have been open to selling the Ivory Coast international this summer but are concrete option to leave has yet to emerge.
