In January, the African Cup of Nations is back, meaning a number of players from the Premier League will head off to Equatorial Guinea for a mid-season tournament which frustrates managers up and down the country.
We'll see the likes of Yaya Toure, Wilfried Bony and Papiss Cisse leave English football for up to a month in order to represent their countries.
Unfortunately for West Ham, they appear to be the team hit with the biggest departures. Only Newcastle have as many players going to the competition (3), but a case can be made that the Hammers' absentees are of much more importance.
Midfielder Cheikhou Kouyate and striker Diafra Sakho will both be representing Senegal next month, but the situation surrounding Alex Song has been a confusing one.
The 27-year-old said that the tournament shouldn't go ahead because of the ongoing ebola crisis in West Africa, and West Ham were keen for him to stay and help them continue their fine start to the season.
Yet now, according to the Telegraph, Song is poised to inform West Ham that he will be going with Cameroon to play in the tournament - which is a huge blow for West Ham boss Sam Allardyce.
Song has been outstanding since joining the Hammers on loan from Barcelona, and could now miss up to a month of action given that he will have to join up with the Cameroon squad in advance of the competition.
