Wolves manager McCarthy has been happy with the general performance of his players in recent games, which have included creditable away draws with Arsenal and Tottenham.
But the 3-2 home setback against Aston Villa last weekend extended Wolves' run without a win to eight games, from which they have collected only four points, and he said: "I don't want people talking to me about how we've played good, bad or indifferent."
McCarthy, whose side entertain Liverpool on Tuesday, added: "We need to win games and we need points.
"I don't want to be in the bottom three at any stage. We are playing well but we are finding every way possible to lose a game and it's costing us.
"Look at the Villa game. There wasn't a lot more that could have gone wrong in the game - a penalty, a sending-off (Karl Henry), someone carried off (Emmanuel Frimpong).
"It was another game we should have won on the back of our terrific first-half performance.
"But it goes down as another heroic failure, which I don't want. It's been the story of our season."
Nenad Milijas is poised to replace midfielder and former skipper Henry, who will have to serve a three-game ban for his sending-off, against the Reds.
The Serbia international is back available after serving his own three-match suspension for a red card against Arsenal.
