Piere-Emerick Aubameyang (Gabon)
Mohamed Elneny (Egypt)
Thomas Partey (Ghana)
Nicolas Pépé (Ivory Coast)
FIFA rules state clubs have to release players by the Monday morning prior to AFCON kick off on January 9th. In this case, that particular Monday is December 27th.
Elneny, Partey and Pépé will almost certainly progress to the knockout stage, meaning that they probably won't be returning to the club before early (or mid) February. Add a week's leave, and we'd be lucky if they're all available before the game against Chelsea at Stamford Bridge on February 12th.
If Gabon finish third—behind Egypt/Ghana and above Sudan—Auba could potentially qualify for the knockout stage based on Gabon's FIFA ranking. Not sure how Gabon's ranking compares to that of other potential third-placed teams, but even if they don't progress to the knockout stage, Aubameyang might not be available before the game against Wolves on February 8th.
