Tigers boss Phil Brown revealed he will now attempt to agree personal terms with the 32-year-old, who has been looking for a new club since being told he could not be guaranteed first-team football at the Riverside.

Brown told BBC Radio Humberside: "The deal between ourselves and Middlesbrough has been agreed.

"It's now just a matter of fine-tuning the deal between us and George and that's a process that does take time."

Boateng cost Boro £5million from Aston Villa in 2002.

His agent Barry Silkman told BBC Sport: "He has a year left on his contract, but he's been there for five or six years and given them good service.

"He played about 80% of the season, but he just thinks that maybe it is the right time to move on.

"Middlesbrough recognise he has been a great professional and say they won't hold out for a king's ransom should he wish to leave and won't stand in his way."

Boro boss Gareth Southgate confirmed on Monday: "George has expressed a desire to move on.

"He's having talks with a couple of other clubs and that is the decision he has got to make now."

Hull have already signing Geovanni on a free transfer and Craig Fagan for £750,000 as they prepare for their first season in the Barclays Premier League.
