The chief has challenged European clubs to match the young star's €50 million buy-out fee, affirming that it was the only way that the Colorado would agree to a sale
The 22-year-old striker has been the subject of heavy speculation over a possible move away from Brazil, with Juventus and AC Milan also part of a list of suitors, which also includes Shakhtar Donetsk.
According to Luigi, however, neither he nor his young star is considering a move away from Beira Rio in the near future.
"We are going to keep Damiao. He would only have two motives to leave: If the club was in a desperate economic situation, which is not the case here, or if he wanted to leave, and that is also not the case," the president fired in an interview with Radio Gaucha on Monday.
Inter have stated in the past that they would only consider a sale if Damiao's buy-out fee was matched, which would mean his admirers would have to pay around €50 million to complete the deal. Luigi trusts that this valuation means his gem will not be going anywhere.
"That is if [the clause] does not become even higher! We have a five-year contract with Damiao and we are not worried."
Inter finished fifth overall in the 2011 Brasileirao, with a penalty from Andres D'Alessandro earning a last-day victory over Gremio and a place in next year's Copa Libertadores.
