Watford are trailing in the race for Reims defender Hassane Kamara.
France Football says the Hornets, Nice and Olympique Marseille are all chasing the 26 year-old's signature ahead of the summer market.
Nice jumped into the lead for Kamara, after informing Reims they're set to make an opening offer.
OGCN are willing to pay €2.3m for Kamara - which is expected to kick Watford and OM into action.
Kamara, a left-sided fullback, has a deal with Reims to 2021.
