The Tigers are preparing for a return to the Premier League after a nine-year absence, having won promotion through the Championship play-offs in May. So far this summer they have brought in goalkeeper Jack Butland from Rangers, midfielder Oscar Zambrano from Maribor and defender Matt Targett following his departure from Newcastle United.
"We are reading dozens of false transfer rumors in many places," Ilicali wrote in a post on X. "We are disturbed by the claims that we have been rejected and by the use of our club's name to gain attention. We have been working intensively for two months.
"I believe we will build a team that we will all be proud of."
Without naming the specific reports he was responding to, Ilicali went on to share what he described as "our latest transfer situation, which includes some clues."
He listed Butland, Zambrano and Targett with ticks alongside their names to confirm those deals, before adding a series of national flags numbered four through 11, each accompanied by a percentage indicating how close Hull were to completing further signings from those countries.
Among the details, the Japan flag was listed at 99 percent, with BBC Radio Humberside sports editor Mike White reporting that Hull have agreed a deal to sign free agent midfielder Hidemasa Morita.
Flags representing Greece and Sweden were shown at 90 percent, while Australia, Croatia and Portugal were each listed at 80 percent, suggesting further deals from those nations remain in progress but are not yet finalised.
The unusual approach reflects Hull City's determination to control the narrative around their summer business as they prepare for the step up in class, with the Turkish owner known for his hands-on style keen to reassure supporters that the club's rebuilding plans remain firmly on track despite the swirl of unconfirmed reports, and prepared to keep using social media as a tool to manage expectations through the rest of the summer.
