Inter have already snapped up Manchester United defender Nemanja Vidic and are keen to add further new recruits to rejuvenate an underachieving squad.
The Italian outfit's transfer guru Piero Ausilio has been spotted at Chelsea's game against Galatasaray and Manchester United's win over Olympiakos and is on a mission in England to improve his chances of some summer signings.
However, the obstacle lies in Eto'o's wage demands which are above the budget given to Ausilio by club owner Erick Thohir.
Ausilio is also reportedly closing in on Manchester United winger Nani, who was linked with the club in the January transfer window.
The report in the Corriere dello Sport suggests that United are keen to sell the Portuguese international on a permanent basis but could consider a loan deal.
It is reported that Nani is open to the move if the two clubs can come to an agreement but Inter coach Walter Mazzarri is yet to give his opinion.
