James, 19, is highly regarded at Stamford Bridge and is set for a bright future in the game.
The boyhood Blues fan, who played alongside England starlet Callum Hudson-Odoi through the youth ranks at the club, has missed just one game across all competitions for the Latics.
James is a tough tackling and forceful full-back, earning rave reviews for his performances throughout this season.
At this tender age he has already been likened to Kyle Walker, called up to train with the England senior squad and, earlier this month, collected his award for making the Championship Team of the Season.
