Reports suggest that Kenny Miller's mooted shift to Fiorentina is being threatened by Rangers. The 31-year old Scotland striker is on the verge of joining the Viola but the Italian club's sporting director, Pantaleo Corvino, suggests that the Ibrox outfit are trying to inch more money out of the proposed deal.

"The reason for the delay is that Rangers keep restructuring the price," he told Italian media.

"We seem now to be moving closer to Valon Behrami at West Ham because Rangers want to raise the offer for Miller."

The transfer fee for Miller is believed to be £700,000 but Fiorentina claim that Rangers keep upping the ante, threatening a move to the Stadio Artemi Franchi.

Some reports also suggest that Rangers have made it clear that they will sell to nobody but Premiership outfit Birmingham City who are still remaining in the hunt for the prolific golascorer.
