Rangers top scorer Kris Boyd is available for sale to Birmingham City should the Championship outfit increase their original offer for the 25 year old.

Ibrox chairman Sir David Murray told BBC Scotland: "Birmingham have made an enquiry. We talked about money but we haven't agreed a fee and no business will be done today.

"We rejected a bid of around £3million but if they improve it, we'll allow them to speak to Kris Boyd."
