Lille are preparing to up their offer for Sochaux right-back Sebastien Corchia, according to French newspaper L'Equipe.
Both Arsenal & Tottenham were put on alert earlier this week after Sochaux rebuffed Lille's opening offer of £1.2m for the 23-year-old full-back.
The Gunners were heavily linked with a move for Corchia last summer and were rumoured to be maintaining an interest as they struggled to tie down Bacary Sagna to a new contract.
Long-standing Arsenal right-back Sagna is out of contract in the summer and is free to negotiate a pre-contract with foreign outfits. With a Arsenal and Sagna rumoured to be quite far away from an agreement, Arsene Wenger could be forced to find a replacement.
However, Lille, determined to land the defender in the current transfer window, are ready to up their initial offer to £1.7m, testing the resolve of Sochaux officials.
Corchia is currently contracted to the Ligue 1 outfit until the summer of 2015 and has already conveyed his intention to leave the club, forcing Sochaux to consider the sale of the promising right-back.
Tottenham, who have also been linked with interest in Corchia may be keeping an eye on the situation as they continue to look for competition for the inconsistent Kyle Walker.
