Defender Daniel Gabbidon has returned to Cardiff after signing a one-year deal as player-coach.
The 35-year-old, who previously played for the Bluebirds between 2000-2005 and made over 200 appearances, returns to south Wales after spells with West Ham, QPR and Crystal Palace.
Gabbidon will combine his playing duties alongside a coaching role with Ole Gunnar Solskjaer's men.
