The Welsh shot-stopper is regarded as County's most prized asset and now clubs are ready to take advantage of Stockport's perilous position by luring him away.
Williams is now set to have his pick of clubs, with Premier League and Championship teams doing battle for his services.
The 22-year-old is currently overcoming a shoulder operation, but he is expected to feature for Wales in the summer and earn his first caps for his country as they face Estonia and Azerbaijan.
But Williams could very well have new employers before his international commitments kick in.
Everton, West Ham, Sunderland, Ipswich and Leeds are all understood to have made contact about a possible deal.
