Birmingham City have confirmed Nikola Zigic and Chris Burke have both left the club.
Both players' contracts ran out this summer and despite being offered new deals by the Blues, they decided against renewing and will both be seeking out new clubs ahead of the coming season.
Zigic had played at St Andrew's since 2010, when he joined from Valencia for £6million. He scored 36 times in 147 appearances including the opener as Birmingham beat Arsenal 2-1 in the Carling Cup Final in 2011.
Burke joined as a free agent from Cardiff in 2011 and played 151 times, scoring 28 goals and earning the player of the season award and players' player of the season in his first year at the club.
