Earlier this week Wembley winning Posh skipper Mick Halsall reminded everyone he started his career at Birmingham, while Siriki Dembele is a recent addition to the ranks of those who have played for both clubs.
But do you remember these players who also signed contracts at Posh and Birmingham? We’re guessing many are long forgotten!

Birmingham City splashed out £250k for a fiesty Welsh midfielder with a very long throw in February 1996, although he only started 26 games for 'The Blues' before moving to Reading. 'The Royals' loaned him to Posh for five games in 1998. He moved permanently to Posh from Cardiff in December 1998. He played 96 times for Posh in total, scoring 5 goals. Photo: PT

THis high-class Irish international right-back was past his best when he moved to Posh from Bournemouth for £25k in August, 1988. He managed just 24 appearances and achieved notoriety for becoming the first Posh sub to then be subbed. Birmingham City had paid a club record £350k to Derby for Langan in 1980. Photo: David Lowndes
