Spurs came close to bringing the Brazil international on board in January, but failed with a deadline day approach.
Officials at White Hart Lane have continued to monitor Damiao since that point, with reports suggesting that they would return to the negotiating table at some stage.
Luigi says further discussions have been held, ahead of the summer window, and he has hinted that the 23-year-old forward will be plying his trade in the Premier League next season - rather than in his homeland or in Serie A.
He told Tutto Mercato: "If a club want a player, they must talk to the president of the club at which that particular player plays, and not just deal with the agent - that is not correct behaviour.
"Recently we talked with Tottenham, Leandro is very likely to play games in England in the coming year. On the other hand, we can exclude Napoli."
