Hull have completed the permanent signing of Tottenham midfielder Jake Livermore.
The 24-year-old, who spent last season on loan at the KC Stadium, has signed for an undisclosed club-record fee, which it is understood could eventually amount to £8million, on a three-year deal.
Livermore told Hull's official website, www.hullcitytigers.com: "I'm delighted to be joining Hull City on a permanent basis. I thoroughly enjoyed my season here on loan and I firmly believe that this club will keep on going from strength to strength.
"I made my feelings known that I wanted to come here permanently and once the two clubs had agreed the fee, it was very straightforward."
Livermore arrived on Humberside in August last year after the Tigers struck a loan deal with Spurs, and excelled in what proved to be the club's best top-flight season yet.
He made 41 senior appearances as Hull finished in 16th place in their first season back in the top flight and reached the FA Cup final.
The club is currently preparing for its maiden European campaign having qualified for the Europa League as a result of its domestic cup exploits.
Manager Steve Bruce knows he will have to strengthen his squad to cope with the extra demands, but securing one of his key men from the last campaign represents a major boost.
City have been linked with a series of potential targets already this summer with Norwich midfielder Robert Snodgrass the latest.
