Samuel Eto'o looks set to be the latest player to depart Anzhi, with the Russian club currently in the midst of a fire sale with the aim of cutting costs.
Inter will compete with Chelsea and Napoli for the Cameroonian's signature, according to the Daily Star.
Eto'o enjoyed a hugely successful spell with the Nerazzurri before departing for Russia, and the proposition of returning to Serie A—where he had a great goalscoring record—could be very attractive.
Eto'o was managed by Jose Mourinho during his spell in Milan, and the Portuguese is now in charge of Chelsea again, which could put Inter and Napoli on the back foot.
None of the interested clubs would likely be able to afford Eto'o's existing wages, but Chelsea would probably be able to trump Inter in that regard.
This would leave Inter's only hope being the nostalgia that the player might have and the legendary status he still holds at the club.
The problem that Inter will have to solve is whether the signing of Eto'o would be worthwhile. After all, his signing alone could not guarantee Champions League football.
If that is the case, Mazzarri might believe that he is better off blooding youngsters such as Mauro Icardi and Ishak Belfodil rather than cramping their development by partnering Rodrigo Palacio with the 32-year-old Anzhi star.
