FRAIZER Campbell has left Sunderland to join Championship leaders Cardiff City.

The striker, whose contract with the Black Cats was due to expire in the summer, has agreed a three-and-a-half year deal at the Cardiff City Stadium.

He leaves Sunderland for an undisclosed fee, which is understood to be around £600,000.

Campbell, who is a full England international, joined Sunderland from Manchester United in 2009 and scored ten goals in his 71 senior appearances for the club.
