Reports have suggested that Bruce could be interested in bringing the England international striker back to St Andrew's following Palace's relegation to the Coca Cola Championship but the Blues chairman claims that the Blues boss has not been mentioned AJ as a possible summer signing.
"Whether Steve would see Andy Johnson as a player that he would like to have at Birmingham then I'm sure he would ask permission from (Palace chairman) Simon Jordan and we'd take it from there," Gold has said.
"But nobody has spoken to me about Andy Johnson."
Bruce sold Johnson to Palace three seasons ago as part of the deal that saw Clinton Morrison move from Selhurst Park to St Andrew's.
