Oli McBurnie's stoppage-time winner in the Championship play-off final against Middlesbrough on May 23 sealed their return to England's top-flight after a decade-long exodus.
Impressively, the Tigers achieved promotion to the Premier League while under a transfer embargo, something no other team has managed in the competition's history.
Nonetheless, with a huge task ahead of them to avoid an instant return to the second tier next season, all eyes are on their summer investment.
Hull could sign as many as 10 players to aid their survival bid under Sergej Jakirovic, and one of those additions could be departing Sunderland midfielder Dan Neil.
The 24-year-old is leaving the Stadium of Light once his contract expires at the end of the month, and according to TEAMtalk, the Tigers are confident of beating Middlesbrough and Rangers to his signature.
Neil was a target of Rangers in January before he joined Ipswich Town on loan, but with City able to offer Premier League football, they could win the race for the Englishman.
Once hailed as "phenomenal" by former teammate Luke Molyneux, Neil was frozen out of Regis Le Bris' plans after helping them win promotion back to the big time, but could finally get his day in the sun with Hull.
