The talented youngster is one of the most sought-after players outside the French top flight, attracting interest from a number of European clubs interested in a potential bargain deal.
According to a report in Voetbal Nieuws, Premier League trio Tottenham Hotspur, Southampton and Manchester City are among those monitoring his situation.
However, an official English bid for the 18-year-old is yet to materialise and the trio risk losing out to Lyon, with the Ligue 1 giants reacting to an initial rejection with a seven-figure bid.
“Lyon has recently made a second offer for Lucas Tousart. Jean-Michel Aulas’s side have offered around £1 million. Valenciennes see it as insufficient and have rejected the proposal,” France Football state.
Who is Lucas Tousart?
The defensive midfielder is one of the brightest prospects in France, representing his country at U19 level and being a regular starter for Valenciennes in Ligue 2.
He is dubbed 'a super talent' by Voetbal Nieuws, a big statement to make considering the French have a proud history of producing world class midfielders.
Should Tottenham Hotspur or Southampton make a move?
Of the three Premier League clubs linked, Tottenham Hotspur and Southampton are the more likely to make a move considering their emphasis on buying and producing the very best young talent.
Spurs need competition for Nabil Bentaleb and Ryan Mason, and the recent departures of Paulinho, Etienne Capoue and Benjamin Stambouli suggests they require extra additions.
Southampton are arguably more settled in terms of midfield numbers, but that should not prevent Ronald Koeman from looking at bolstering his U21 side as he bids to build a healthy future on the South Coast.
