Chelsea and Manchester United are in a two-horse race for Lille's Soumare, according to Sky Sports.
Arsenal were previously thought to be weighing up a move early in the winter transfer window, but have since cooled their interest.
It's reported that both Chelsea and United have had discussions regarding Soumare, but Lille won't make a decision before they play Paris St Germain on 26th January.
Chelsea are keen to invest for the future as rumours regarding N'Golo Kante's future continue to surface and resurface.
The blooding of a young player at such a high level is indicative of how much Lille rely upon the Frenchman.
Soumare has two and a half years left on his current contract and is valued at around £20m.
