Sofiane Boufal has emerged as a target for Tottenham.
Spurs are said to have sent scouts to watch him in action, and plan to do so again this coming weekend.
The 21-year-old is an attacking midfielder who would provide competition for Christian Eriksen.
Born in Paris, he has pledged his international future to Morocco, although is yet to represent his country.
He ended last season in terrific form, scoring three goals and providing six assists in his final seven games.
A sticking point could be his long term contract at Lille which runs until 2019.
Spurs have other irons in the fire at present, battling to sign Saido Berahino from West Brom, and linked strongly with a deal to sign Heung Son Min from Bayer Leverkusen, as reported The BBC.
The club have completed one deal from Ligue 1 already this month, signing Clinton N'Jie from Lyon.
Whether a late move for Boufal before the transfer deadline is on the cards is unclear, or if Spurs are simply doing their scouting and research with a view to a move in the future should they be convinced enough, or get wind of Boufal's desire to move on.
