Nerazzurri director Piero Ausilio says the club may struggle to move for either striker due to the wages they receive at Man City and Chelsea respectively
Only one Nerazzurri player - Argentine Rodrigo Palacio - has scored more than five goals in Serie A this term as Walter Mazzarri's side sits fifth in the table.
New Inter owner Erick Thohir is remaining coy on transfer targets despite being expected to splash the cash in the offseason, and moves for Manchester City's Dzeko or Chelsea forward Torres appear unlikely, despite reports linking the club with both.
When asked by La Gazzetta dello Sport if bids for the likes of Dzeko, Torres, Javier Hernandez and Mario Mandzukic were dreams or aims, Ausilio said: "People who earn 5-6 euro million a year for us are over budget. And under normal circumstances we cannot take them. And I do not think it is so easy getting these players on loan."
Ausilio confirmed a frontman was high on Inter's priority list ahead of the 2014-15 campaign, though, adding: "We need a striker who has a lot of goals.
"There have been a number of absences between Diego Milito and Mauro Icardi this season."
Jose Mourinho is planning an overhaul of his Stamford Bridge playing squad this summer and Torres has interested Inter, but the club wants to negotiate a deal in which Chelsea subsidize Torres' wages either through a loan to the Serie A club or a transfer complete with lucrative golden handshake.
Ausilio also stated there was a "mutual willingness" to extend midfielder Fredy Guarin's contract at the club.
Guarin seemed set for Juventus in January but a swap deal - that would have seen forward Mirko Vucinic join Inter - was prevented at the last minute by Inter's president.
