"Manchester United, Chelsea, Arsenal and Liverpool can perhaps say that certain players aren't for sale and never will be at any price," said Coleman to the CT, "but clubs outside of that top four can't afford to do that.
"I've no intention of selling Kieren Westwood, Scott Dann, Danny Fox, Aaron Gunnarsson - we're trying to build a team around these boys because they're all of a good age and they're only going to get better.
