The 21-year-old attacker, who primarily operates on the left flank, has recently committed his international future to Belgium and is expected to represent the Red Devils at the FIFA World Cup.
Serie A side Como, who will compete in the UEFA Champions League next season, are among the clubs monitoring his situation, while Manchester United and Manchester City are also reportedly tracking the forward, as per La Gazzetta dello Sport.
Foot Mercato adds that Liverpool have now entered the race, joining a competitive list that also includes Borussia Dortmund and Bayern Munich.
Despite the mounting speculation, the player remains fully focused on preparing for the World Cup with Belgium, while Lille maintain a firm stance on their €70m asking price.
