Ken Dulieu has admitted that Coventry City have offered Sammy Clingan and Martin Cranie new deals worth £8k a week.
Speaking to the CT, Mr Dulieu said: "Sammy and Martin have had contracts on the table for four months and they are really good contracts.
"If you look at the average Championship contract being £4k a week I can tell you they are double and we can't go much higher than that.
"It's no good saying we can go to ten, twelve or fourteen."
