Charlton Athletic have announced the appointment of Russell Slade as the club's new manager.

The 55-year-old has taken charge of the newly-relegated League One club just 28 days after he was appointed 'head of football' at Cardiff City.

Prior to the promotion, Slade was head coach of Cardiff for almost two years, but has now signed a three-year contract with the Addicks, who began searching for Jose Riga's replacement after the club dropped out of the Championship with a 22nd-place finish.
