Blues can confirm that a number of players are to leave the club following the expiry of their contracts.
Franck Queudrue, Gary McSheffrey, Gregory Vignal, Artur Krysiak and Jared Wilson will depart St. Andrew's on 30 June.
Queudrue, who joined Blues from Fulham in 2007 made a total of 51 appearances during his time at the club, scoring three goals.
The likeable Frenchman was named as the club's Player of the Year for the 2008/09 season.
In March 2010, he joined League One side Colchester United on loan but was restricted to just three appearances because of injury.
He was the club's top scorer in the 2006-07 season with a 16-goal haul.
In total he played 96 times for Blues, scoring 20 goals.
In January 2010 he joined Leeds United on loan, where he made 11 appearances and scored a solitary goal as the Whites were promoted back to the Championship.
Defender Gregory Vignal moved to Blues in August 2009 from French side FC Lens on a one-year-deal.
The Frenchman found his playing chances limited to just nine outings during the successful 2009/10 campaign because of injury and the form of Liam Ridgewell.
Young Polish goalkeeper Artur Krysiak joined Blues' Academy in August 2006.
He was with League Two side Burton Albion on loan throughout the 2009/10 campaign, where he made 40 appearances before picking up ankle injury last month.
The final player to leave the club is right back Jared Wilson.
The 21-year-old Cheltenham born full back is a product of Blues' Academy, which he joined at the age of just 12-years-old.
He made his one and only first team appearance in October 2008 after coming on as first half substitute during Blues' Championship game against QPR.
Blues have previously confirmed the exits of Joe Hart, Lee Carsley, Shaun Timmins and Jacob Rowe from the professional playing staff.
Meanwhile Teemu Tainio has returned to Sunderland following the end of his season long loan at St. Andrew's.
The Finnish international made a total of six appearances for Blues.
