The Nerazzurri were hoping to lure the Argentinian winger back to Serie A after Lamela's dismal first season in the Premier League.
The 22-year-old, who moved to the London outfit on a club-record £30m transfer deal from Roma last summer, made just nine league appearances for Spurs in the 2013-14 campaign.
"Lamela is a dream that we haven't been given a chance to realise," Inter sporting director Piero Ausilio said to Gazzetta dello Sport. "Simply because Tottenham don't want to put him in the market."
Ausilio also revealed that Inter have rejected tempting offers from several clubs for their Croatian midfielder Mateo Kovacic.
When asked if Kovacic is not for sale, Ausilio said: "Absolutely. In fact we have turned down various offers from big clubs."
Ausilio also said Inter's talks with Porto to acquire Portuguese central defender Rolando have reached an impasse.
"The negotiations are at a standstill," he said. "We easily reached an agreement with the player and made an offer to Porto that we considered fair for a defender who is 28 and whose contract will soon expire.
"We simply don't want to go over that figure."
