Rumours that Tottenham have renewed their long-standing interest in Damiao has intensified in recent weeks.
That speculation looks set to gather more pace in the coming days after Emmanuel Adebayor's decision to go to the African Nations Cup with Togo left Spurs boss Andre Villas-Boas with one recognised striker - Jermain Defoe.
Damiao has denied that there have been any firm bids lodged for the him, but when asked whether he could guarantee Internacional fans he would be playing for them in the upcoming season, the 23-year-old stopped well short of committing his long-term future to the club.
"I guarantee that, for now," Damiao told Brazilian website Zero Hora. "There has been no proposal, no negotiations. I am only thinking about Internacional.
"The president is the one who decides."
Internacional, who signed the striker four years ago, appear to be playing hardball in their attempt to keep hold of the hitman, with club president Giovanni Luigi reported to have said that only a "spectacular" offer will tempt him to part ways with the striker who was top scorer at London 2012.
Adebayor, meanwhile, has finally decided to play in the African Nations Cup.
After weeks of indecision, the 28-year-old has agreed to play in the tournament, which runs between January 19 and February 10, after receiving assurances from Togo president Faure Gnassingbe about team security at the tournament.
"I have met the head of state on two occasions. We talked, I told him what was wrong with Togolese football," said Adebayor, who was on the Togo team bus that was ambushed by armed gunman at the 2010 tournament in Angola."
