Watford are closing in on a move for Ivory Coast international Brice Dja Djédjé.
The defender made 22 appearances for Marseille last season but he is ready to leave after attracting interest from England.
Watford have been working on a deal for the Ivorian since May after scouts returned from trips to France with glowing reports.
The Premier League club had an initial offer for Dja Djédjé rejected but after further talks a fee has now been agreed.
That amount, according to L’Equipe, is reportedly around GBP£3.3m but it could rise to over £4m if various bonuses are met.
Dja Djédjé is now scheduled to have talks with Watford this week as he and his agent discuss personal terms with the club.
The right-back is, however, said to be very keen on a move to England and there are expected to be no difficulties in reaching an agreement.
Capped seven times by the Ivory Coast, Marseille would have liked to keep hold of Dja Djédjé but they have been forced to sell in an attempt to balance their books.
The French club have already sold Michy Batshuayi to Chelsea for £33.2m and they are now on a more stable footing.
To cope with the loss of Dja Djédjé, Marseille have already tied up a deal for fellow right-back Hiroki Sakai.
The Japan international has signed on a free transfer after his contract with German club Hannover expired.
