Birmingham City midfielder Michel has joined Spanish La Liga side Getafe for an undisclosed fee.
The 25-year-old arrived in January 2010 from Sporting Gijon for £3m but made just 12 appearances for Blues.
Michel, whose full name is Miguel Marcos Madera, was brought to St Andrews by former manager Alex McLeish.
But he failed to make an impression and spent the second half of last season on loan at AEK Athens, featuring 15 times for the Greek side.
The Spaniard had made 138 appearances for Sporting Gijon during five years at the club, and scored seven times for the La Liga side before his move to England.
