The Premier League is set for a mass exodus to Ghana with the Africa Cup of Nations just around the corner.
Ghana hosts the 2008 tournament which runs from January 20 to February 10, with holders Egypt looking to retain their crown.
Around 40 Premier League players could leave the domestic season in England to link up with their national team.
Portsmouth could be most affected with five of Harry Redknapp's squad likely to be called up for national duty.
Chelsea will also be heavily burdened by the competition with four members of Avram Grant's squad set to fly out to Ghana.
Egypt won the tournament in 2006, beating the Ivory Coast on penalties and Middlesbrough could lose Mohamed Shawky and Mido to the holders.
The exodus could spark much activity in the January transfer window with Redknapp and Grant already stating that they are likely to bring in fresh faces to cover for the players heading out to Ghana.
Only four Premier League clubs (Aston Villa, Derby County, Fulham and Manchester City) are not affected by the tournament.

Kolo Toure and Emmanuel Eboue (Ivory Coast), Alexandre Song (Cameroon)
