Following the news that Anzhi Makhachkala's owner has started 'reformatting' the club - including sacking former Manchester United coach Rene Meulensteen after just 16 days in charge - a number of Europe's elite are on alert in an attempt to snap up a bargain.
The likes of Willian, Lassana Diarra and Eto'o are all up for grabs, as Anzhi attempt to cut their annual budget from to $50-70 million from their previous outlay of $180 million.
The Russian outfit have started the season in poor form on the pitch too, losing four out of four in the league, and a number of their star players are looking to secure a quick exit from the crisis club.
Napoli have also been linked with a move fro Eto'o, but Spanish media outlet El Confidencial are reporting that Arsenal and Chelsea lead the way in pursuit of the former Barcelona star.
The report also suggests that Chelsea are slight favourites to secure the signature of Eto'o ahead of the north London club.
Arsenal are on the lookout for a new striker, with boss Arsene Wenger continuing his pursuit of Liverpool's wantaway frontman, Luis Suarez.
Eto'o, 32, has already scored twice for Anzhi this season, despite the team's poor start, and he has seemingly picked up where he left off last season, having notched 18 goals in 29 games for both club and country last season.
