Wolves chief Jez Moxey says they're investigating Stefan Maierhofer's critical interview this week.
The new Bristol City signing accused Wolves boss Mick McCarthy of "taking the p***" over his lack of games since his summer arrival.
"Of course we have spoken to Stefan and his agent, we have seen a basis of an interview he gave abroad and translated that, but can't find anything that actually corroborates what is being reported," Moxey told the Express & Star.
"We have spoken to all sorts of people and we can't see where anyone has said this.
"Bristol City's people have given us information about the comments Stefan made and nothing was said in that regard, so it seems like someone has taken a liberty in the extreme.
"But we will continue to look into it but as far as we are concerned, this sort of thing would be dealt with internally and we will not be making any further comment about it.
"All we are interested in is preparing for Saturday's game against Villa."
