Yes but...Bissouma and Sarr are not missing 8 games. There'll be a winter break this season from Jan. 13-20. AFCON has its opening ceremony on Jan. 13. This season the AFCON final will be delayed to Feb. 11. Generally it takes 9 days from the first match to the semi-final, so at most they'll miss two days, and then probably like four days in February if they make it to the final.
Historically there has been a problem with players returning from AFCON to the PL & being physically & emotionally shattered, and never really getting back up to speed until the following season.
Bissouma & Sarr seem good, professional, characters. Not your Adebayors....
But AFCON during the PL season has always been disruptive.
