Milan Calasan has already confirmed that Zigic has no intention of playing in the Championship with Birmingham.
"A few English teams are showing interest in Zigic, but the obstacle now is his high wage at Birmingham," Calasan told Serbian daily Blic.
"Zigic certainly won't be playing in the Championship. There are clubs in England which are willing to meet the demands for him, and it is possible he will be continuing his career in the Premier League."
"As for Redknapp, he is also heaping praise on Zigic, but he already has Crouch among his ranks."
Calasan admitted that Zigic does have interest from Germany but played down links with Nurnberg or Hannover.
"Much bigger clubs than those mentioned are in play, but it is not the right moment to reveal any names right now," he said.
"His career may well continue in a Bundesliga side."
