Tottenham Hotspur are stepping up interest in Sofiane Boufal, report French website Footmercato.
Boufal, 22, is highly rated by Lille and has been compared to Eden Hazard, a former star at the Ligue 1 club.
Footmercato report there is considerable interest from clubs in Boufal, but that there is one side leading negotiations, and that is Tottenham.
It is reported that Spurs have put forward an offer of 20 million Euros [£15.7m] plus performance related bonuses, and offered a five-year contract to the player.
Boufal is claimed to be keen, with the chance to play in next season's Champions League with the club a key attraction.
Club president Michel Seydoux is quoted saying it would be 'impossible' to retain Boufal this summer, describing the gap between English clubs in terms of finances and being too great.
Boufal is an attacking midfielder capable of playing on the left or right wing, and has scored 11 goals in 25 starts for Lille this season, also providing four assists.
Three of these goals came in the form of an impressive hat-trick in a 4-2 away win over Ajaccio at the weekend, which underlined what a big loss he would be to his club if he leaves.
