It appears the deal will be completed in the next few days after Cisse passed a medical at the Reebok Stadium last week.
Chairman Phil Gartside told SkySports.com
"Birmingham have accepted our offer and it is just a matter of finalising things," said Gartside.
"The player has been for a medical and passed with flying colours.
"Now things are up to Sam really."
Finally things start to be looking up on the transfer front after todays capture of Michael Bridges.
