The Africa Cup of Nations begins next month, with about 40 Premier League players set to miss several weeks of the season as they head to Cameroon.
Watford have the most players eligible - six - although two are likely to miss out through injury.
Arsenal, Crystal Palace and Leicester are all set to wave four players off too, while Liverpool will lose three - including Mohamed Salah and Sadio Mane.
Chelsea are likely to be without keeper Edouard Mendy and Hakim Ziyech.
They could miss the Fifa Club World Cup and league games against Liverpool, Manchester City and Tottenham, among others.
Leeds, Newcastle, Norwich and Tottenham will not lose anybody.
As things stand, players could go after the games on 26 December, and those who reach the final may not be available again until Saturday, 12 February.
While the Africa Cup of Nations does not start until Sunday, 9 January, Fifa rules say clubs must release their players by Monday morning of the week preceding the week the tournament starts - which is 27 December.
Players can come back to England the day after their teams are knocked out, with the final and third-place play-off on Sunday, 6 February.
However, many clubs are currently negotiating with various national teams to try to delay the date they have to release their players.
The European Club Association (ECA) has expressed its "deep concerns" regarding player welfare before the tournament because of the "worsening public health situation" around Covid and is seeking urgent talks with world governing body Fifa.
No squads have been named yet but these are the players who could be gone.
