Ken Bates has threatened to report Neil Kilkenny to the Football Association for his goal celebration on his return to Leeds.
The 25-year-old failed to agree a new contract at Elland Road after rejecting their initial terms and was not offered an improved deal.
Kilkenny subsequently joined Bristol City on a three-year deal and marked his return to the club with a goal, which he celebrated by blowing kisses at chairman Bates and chief executive Shaun Harvey in the stands.
"He can't justify or excuse his behaviour. It shows exactly why we aren't sad to see him go," Bates said in the Yorkshire Evening Post.
"Neither myself nor Shaun ever goes down to see the players on match days. Why would we?
"The fact is he asked for a wage which we didn't think he was worth. He's a petulant sod with big ideas of himself.
"We might report his behaviour to the Football Association because we've got CCTV footage of it."
The Australia international explained his actions by saying Bates and Harvey had purposely ignored him prior to the game.
"I didn't want to celebrate in front of the fans but I needed to make a point to the chairman and his chief executive because everybody here said hello to me except for the chairman and chief executive, which is disappointing," said Kilkenny.
"I've seen that the chairman said I left Leeds to join a smaller club and that is disrespectful to me and Bristol City.
"That's really disappointing but that's him - what can you do? I did blow a kiss, but I can't stress enough that it wasn't to the fans."
