Crystal Palace chairman Simon Jordan has slammed Birmingham City's board as "imbeciles".
Jordan added he would like to punch Blues co-owner David Sullivan and said "the best thing about Birmingham is the road out".
There has been bad blood between the two clubs since Birmingham poached manager Steve Bruce three years ago.
At the launch of the new Champions League manager game, Jordan told the Mirror: "I have got no issues with Steve Bruce - I have got an issue with the imbeciles he works for.
"I think they are disingenuous. The ethics with which they do business, I don't appreciate. I have had enough dealings with them to be able to have that view.
"Am I surprised? They sell dildos for a living. That gives you a judgement on what they may or may not be."
Sullivan, who is president of Birmingham, has made part of his fortune in the porn industry. And, unsurprisingly, Jordan will have little sympathy if Birmingham do go down.
"I think in life you get what you deserve," he said. "Despite my distaste for the owners, I don't wish any club bad luck. If Birmingham go down, am I going to shed a tear? No. Because the best thing about Birmingham is the road out.
"The reality is that if they go down, they deserve to go down."
