It is the time that managers of Premier League teams dread, when some of their top talent will miss key games due to the awkwardly timed African Cup of Nations tournament taking place between late January and early February.
English-based players have already left for Africa to practice with their international teammates and won't be back until their team is out of the tournament. This weekend sees the first league games that many of the African players will miss.
Although fewer players are departing for Africa from the Premier League than from other European leagues (such as France's Ligue 1), teams have still been affected in England by the competition. No doubt, it would be easier for them if the tournament were played in the summer.
Nonetheless, the tournament has been played at this time of year for a while now, and each manager has accounted for this.
Here are the top four players going back to Africa who'll be missed in the next few weeks.
