Cameroon striker Samuel Eto'o is poised for a reunion with Jose Mourinho and sign for Chelsea, according to Sky sources.
The west London side recently acquired Willian from Anzhi Makhachkala and now look set for another deal with the Russian team for Eto'o.
Recent reports have suggested the 32-year-old was weighing up a return to Inter Milan, but after appearing to be out of the race to sign Manchester United's Wayne Rooney, Chelsea have made their move for a new striker.
Four-time African Footballer of the Year Eto'o was an integral part of Mourinho's Champions League-winning Inter side in 2010, before heading to Anzhi the following year to become the highest-paid player in the world.
Anzhi are in the process of slashing their wage bill with owner Suleyman Kerimov desperate to balance the books of the financially-troubled club.
Sky sources understand that Eto'o will be officially revealed as a Chelsea player by Friday lunchtime.
