Lille coach Frederic Antonetti admits highly rated Moroccan midfielder Sofiane Boufal is likely to "be transferred at the end of season".
The 22-year-old joined Lille from Angers in January 2015 and he has turned into one of their star attractions, scoring 12 goals in 45 appearances for the Ligue 1 outfit.
However, he has been linked with a host of clubs with the likes of Manchester United, Borussia Dortmund, Juventus and Arsenal all keeping tabs on him.
And Antonetti admits Boufal, who only made his Morocco debut in March this year, is set to leave come the end of the campaign.
"Keep Sofiane? It is going to be difficult," he told RMC.
"We all know that in France, we must balance the budget at the end of the season. It is expected that Boufal will be transferred at the end of season. This is part of the DNA of Ligue 1.
"The best players, at some point, are drawn to the richest championships."
