Egypt international midfielder Ahmed Elmohamady is set to sign a permanent deal with Hull after spending a year on loan at the KC Stadium from Sunderland.
The 25-year-old scored three goals in 41 games last season as he helped Hull win promotion to the Premier League.
Hull believe they have an agreement in principle with Sunderland over the fee, and now they will look to put together a package to tempt the player.
It would be the second time manager Steve Bruce has signed the player.
In 2010, then-Sunderland boss Bruce brought Elmohamady to the Stadium of Light, initially on a loan deal before completing a £2m permanent move for the player the following year.
The only sticking point for Hull could be Elmohamady's wage demands.
Hull's managing director Nick Thompson told the Hull Daily Mail: "We are in the process of negotiating a deal. We know where we stand with Sunderland on the price and now it's a case of agreeing a deal with the player and his agent.
"When it comes to a contract, Premier League expectations from players sometimes will not match up with our expectations.
"It's a case of talking and coming to a point where you can agree a reasonable position."
