Real Madrid are reportedly keeping an eye on Lille trio Boubakary Soumare, Victor Osimhen and Gabriel as they look to build for the future.
Los Blancos are known to be keen on signing younger players that they can develop into stars at the Santiago Bernabeu for years to come.
Spanish outlet Marca reports that the Spanish giants have been monitoring all three players this season and they have sent scouts to some of Lille's matches.
Nigerian striker Osimhen, 21, has netted 13 goals in 24 appearances this season, while Brazilian defender Gabriel has been an almost ever-present for the club who are currently fourth in Ligue 1.
Twenty-year-old midfielder Soumare joined Lille in July 2017 from Paris Saint-Germain after realising that his first-team opportunities at the Parc des Princes would be limited.
Of the three, Madrid are likely to face the greatest competition for Soumare's signature as both Manchester United and Valencia are known to be interested in the Frenchman.
