Lille fear their squad being ripped apart this summer by Premier League clubs.
Le 10 Sport says as many as four players could be destined for England this summer.
Headlining the potential sales is star Nicolas Pepe, who along with Bayern Munich, has attracted approaches from Manchester United and Arsenal. Both English giants have opened talks with Lille for the Ivorian.
Everton, Chelsea and the Gunners have also expressed interest in Lille midfielder Thiago Mendes.
Cardiff City offered €10m for Zeki Celik in January and could try again this summer should they stay up. And Jonathan Bamba is another attracting English enquiries.
