Coventry chairman Ray Ranson dismissed speculation that defensive duo Daniel Fox and Scott Dann will be sold over the summer.
The pair, who have both been capped by England U-21s this season, have been subject to repeated reports of interest by a number of Premier League clubs including Wigan, Bolton and Sunderland.
Ranson has insisted City will be adding to their squad this summer and not selling two of their most prized assets.
'They are not for sale, end of story,' Ranson told the Coventry Telegraph.
It wouldn't surprise me if they are attracting interest but we have made a lot of decisions on staff for next year and we are looking to recruit, not sell.
'We are building a talented young side and for anyone to suggest we are looking to sell our best players just doesn't stack up.'
