Watford have tabled a bid for Lille winger Sofiane Boufal.
The Morocco international has been linked with a big money move to PSG in recent days.
However, France Football says Watford are the first club to table a concrete bid.
The Hornets offered €9 million for Boufal, though LOSC are seeking closer to €20 million to sell.
"A good sale is planned for Boufal. But nothing is certain," declared Lille president Michel Seydoux last week.
