West Ham United are closing in on a deal for Portsmouth midfielder Kevin-Prince Boateng.

The Sun says Pompey insist they will not sell their prize asset on the cheap as they plan a mass clearout this summer.

Boateng, 23, has been one of the few successes of a dismal season at Fratton Park since his £4million move from Spurs last year.

And Pompey administrator Andrew Andronikou is hoping to start a bidding war for the £6m-rated former German Under-21 star, who will play his final game for the club in next month's FA Cup final against Chelsea.

West Ham are leading the chase for Boateng - but must fight off Birmingham, Sunderland and Stoke.
