Marseille midfielder Morgan Sanson is attracting interest from Premier League clubs.
The 26-year-old was a long-time target for West Ham and could yet come into their thinking towards the end of the window but the French club want around £25million.
With budgets tight at most clubs that has slowed down negotiations. Wolves, Arsenal, Fulham and Burnley are among those who have considered the former France Under 21 international as they strive to improve their central midfield options.
Marseille are open to negotiating as they look to re-shape their squad amid financial fair play concerns.
Sanson has been a key figure under Andre Villas-Boas during his tenure at Marseille with the side finishing second in the French league last season to qualify for the Champions League.
Burnley made their enquiries earlier in the window but Sanson's valuation was too steep for them and it is understood Sanson was not overly keen on the move.
Arsenal made initial soundings regarding Sanson early on in the summer as they look to sell Lucas Torreira and Matteo Guendouzi but their budget is restricted.
They have explored the possibility of exchanging players plus cash for Atletico Madrid's Thomas Partey while Bayern Munich's Thiago Alcantara, who has interest from Liverpool, has also been discussed.
