Tottenham boss Harry Redknapp has continued trimming this squad at White Hart Lane by offloading Germany Under-21 midfielder Kevin-Prince Boateng to Portsmouth for £4million.

'Arry has already sold Darren Bent and Pascal Chimbonda and now looks set to shed some more dead wood in the form of Boateng.

The 22-year-old joined Spurs in the summer of 2007 in a £5.5million deal from Hertha Berlin but has failed to make the impact that was expected of him and spent last season on loan at Borussia Dortmund.

Boateng is way down the pecking order at the North London outfit and is currently holding talks and undergoing a medical at Fratton Park as he looks to kick-start his career under Pompey boss Paul Hart.

"Portsmouth are trying to sign Boateng for something in the region of £4m," Redknapp admitted.

"I don’t know how far our chairman and Peter Storrie (Pompey’s chief executive) have got with that one, but it's on the go at the moment."

Meanwhile, the South Coast club are also closing in on a loan deal for Boateng's Spurs' team-mate Jamie O'Hara, who could be interested in a temporary switch to Pompey in the hope of gaining regular first-team football.

Redknapp admitted that he was reluctant to let O'Hara go, having rejected a £4million bid for the 22-year-old from Fulham in January, but is happy to let him join his old club on loan

"Jamie's a terrific player but needs to play games and I'll let him go to Portsmouth on loan. He'll do a great job for them," said Redknapp.
