West Ham United have confirmed the signing of Stephen Henderson from Portsmouth on a permanent basis.

The 24-year-old goalkeeper had initially joined the Hammers on a loan basis in March of this year.

"I'm chuffed to bits to get it wrapped up," Henderson told the club's official website. "I'm a very happy man today. It's been absolutely brilliant since I joined and it obviously topped it off on Saturday with us getting to the Premier League.

"The lads have been brilliant with me and have made me feel welcome so I'm very happy."

The 24-year-old, who has penned a three-year contract, failed to make one appearance during his loan spell at Upton Park.
