City are looking at two defenders to come in on loan but are yet to land them.
"We haven't got anybody in yet and we're not prepared to pay inflated prices of £15-20,000 a week to come in on loan," said Coleman to the CT. "Two players we have looked at have been out for two months, so I don't think that's the right way to go."
With Stephen Wright suspended, Curtis Wynter is expected to start against Blackpool on Saturday at right back with Aron Gunnarsson who had to pull out of training today, playing at centre half.
