Swansea manager Brendan Rodgers has accused Wolves fans of being disrespectful towards Mick McCarthy during Saturday's 2-2 draw at Molineux.
Manager McCarthy had come under pressure following five consecutive Barclays Premier League defeats, and sections of the home support chanted "You're getting sacked in the morning" before Wanderers fought back from 2-0 down to snatch a point.
Rodgers said: "Mick McCarthy has given the club so much. I couldn't believe the way they were standing and singing out there."
He added: "I felt for Mick. We were playing well and dominating, but he has made decisions to take this club out of the Championship and make them an established Premier League club. So to show that disrespect when he is trying to change the game, I thought it was sad.
"Wolves is a club with a wonderful tradition and the supporters are passionate but in the last five years Mick McCarthy has given this club everything.
"He works hard every day and he puts out competitive teams to keep them in the league, which he has done in the last couple of years. I find it astonishing that he gets that amount of stick."
McCarthy was in a thunderous mood despite Wolves' late revival, and attempted to brush aside questions about his treatment from his own supporters.
But he did say: "They (the fans) can react all they like, it was a great point and I am delighted. I can't explain the comeback. We were really, really lucky.
"We have played better over the previous five games and got nothing. We have needed something to get us off seven points, something to end the run of defeats.
"We needed a bit of luck or a bit of magic and if this proves to be a turning point I will be delighted."
