The Giuseppe Meazza chief confirmed that his club are interested in bringing the attacking midfielder, as well as another "great player", to San Siro ahead of the 2014-15 campaign
The Giuseppe Meazza side are keen to strengthen their squad ahead of the 2014-15 campaign and have been linked with a host of players, including Fernando Torres, Edin Dzeko and Alvaro Morata.
Hamsik is also believed to be a target for the Nerazzurri and Thohir has now revealed that he is keen to lure the Slovakia international away from his current club - though he won't be the only "great player" Inter try to bring to San Siro this summer.
"We will have a good transfer campaign and we will sign two great players," Thohir told reporters.
"I would like Hamsik at Inter, but I also like some of the other names that have been mentioned in the press. They could all add something to Inter.
"I will not confirm anything until a deal is completed. The objective is to build a balanced team that is able to compete and can do well."
Hamsik, 26, has a contract with Napoli until the summer of 2018. He has netted six goals in 26 Serie A appearances for Rafa Benitez's men this season.
