English Premier League side Middlesbrough have said defensive midfielder George Boateng can talk to other clubs. The Netherlands international, 32, has spent six years at Boro, but he has grown frustrated at not being guaranteed a first-team spot.

Clubs expressing interest in Boateng include Hull City, who were recently promoted into the English top flight, and Scottish champions Celtic. The player joined Middlesbrough from Coventry City.

Boro coach Gareth Southgate told the club's official website: "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."
