Jordan Mutch, who had a spell on loan with Hereford United, has joined Cardiff City from Birmingham for a fee in excess of £1M.
The 20 year old mid-fielder has signed a three year deal with the Bluebirds.
Mutch came to Edgar Street in late November 2009 on a Football League Youth Loan deal which meant he could play for Birmingham youth and reserve teams if Hereford hadn't got a fixture on that day.
His first game for the Bulls was against Colchester in the FA Cup. A few days later he made his League debut in a 3-1 away win at Northampton.
