Birmingham City have completed the signing of Championship [second division] Cardiff City defender Roger Johnson in a £5million [$8.13 million] deal, representing manager Alex McLeish's sixth signing since winning promotion to the top flight last season.

The 26-year-old central defender, who spent three years with Cardiff, has put pen to paper on a three-year deal which will keep him at St Andrews until the summer of 2012.

"Premier League football is the dream at the start of any footballer's career, so I am pleased I have been given that chance with Birmingham," Johnson said.

Johnson is the third centre-back to join City's ranks this summer following Scott Dann and Giovanny Espinoza.
