It is not the first time this season that Republic of Ireland striker Keogh has come under harsh scrutiny from Wolves fans and McCarthy wants everyone in WV1 pulling in the same direction.
"Andy's different class, he plays his part and works his shift and I thought having come off they (the crowd) then responded in the right way to him," said McCarthy. "I'm not getting involved in all that.
"We've got 15 games left to play. There's two scenarios here - we win and we go up and everybody's happy or we don't and we'll all be unhappy.
"Let's just stick together and keep cracking on, the lads are all as close as ever. Keogh will still be a big player for us."
