Portsmouth sign defender Ben Haim

Portsmouth have signed Manchester City's Israeli international defender Tal Ben Haim on a four-year contract.

The 27-year-old, who has also played for Bolton and Chelsea, last featured for City in December, before going out on loan to Sunderland.

Ben Haim could make his Pompey debut on 12 September against Bolton, the club that brought him to England in 2004.

The Israeli centre-back then signed for Chelsea in 2007, before moving to City a year later.

Portsmouth have lost their opening four Premier League games, most recently to City on Sunday, and have sold experienced defender Sylvain Distin to Everton.

"It's a big challenge," said Ben Haim. "I think we can turn things around."
