Fulham say they did not renege on a three-day trial for Aberdeen's Kevin McNaughton - because they have no interest in the 23-year-old defender.
Kevin McNaughton is out of contract in the summer
Dons boss Jimmy Calderwood had claimed that a change of heart by Fulham had left a "bad taste in the mouth" and the player also expressed disappointment.
But a Fulham statement said: "We are perplexed by the comments allegedly coming from Aberdeen.
"As no dialogue whatsoever had taken place between ourselves and Aberdeen."
Calderwood believed that Scotland defender McNaughton, who rejected a new Dons contract, would train with Fulham in the hope of securing a £200,000 move to the English Premiership club.
But Fulham stated: "McNaughton's agent had made a speculative approach to ascertain any potential interest in seeing the player train. Nothing at this time was agreed.
"Fulham would like to make it clear that, if we were interested in a player at another club, a direct approach to that club would be made and we would not attempt to secure the services of a player through any other route.
"If the club had decided that it wanted to see Kevin McNaughton, it would then have been the responsibility of the senior management team at Fulham to liaise directly with Aberdeen.
"As there was no interest, no contact was made. Therefore, we are disappointed that these comments have appeared in today's press."
The Aberdeen website had claimed that Fulham had changed their mind after deciding to renew their interest in Chelsea's Wayne Bridge.
And the Scottish Premier League club responded further: "The club has spoken to the player's agent, who has confirmed categorically that Fulham did ask him to arrange for Kevin to travel down to London for a few days.
"As is normal in such an instance, he then asked the club for permission for this to happen, which was granted.
"However, on Sunday the agent received a further phone call informing him that Fulham had changed their mind."
McNaughton is also reported to be the subject of interest from the Norwegian club Molde, who are managed by the former Aberdeen striker Arild Stavrum.
Meanwhile, Aberdeen keeper Ryan Esson has turned down a new deal with the Dons after losing his first-team place to Jamie Langfield.
