Negotiations between Inter and Anzhi for £29m-rated Samuel Eto'o resumed today and it's reported the final offer will be made tonight.
The two clubs hit problems during the talks after a deal appeared to be struck earlier in the week.
According to the Gazzetta dello Sport, this is the decisive day, as the move could either be completed or collapse permanently.
Inter are holding out for €29m for Eto'o, while so far Russian outfit Anzhi have proposed €24m.
It is hoped they could reach an agreement worth €27m, splitting the difference.
Negotiations stepped up a notch after a lunch meeting in Milan between agent Claudio Vigorelli, FIFA agent Peppino Tirri and representatives from both clubs.
However, Anzhi are expected to make their ‘take it or leave it' offer tonight.
