The Latics sent Wolves to the bottom of the Barclays Premier League with a 2-1 win at Molineux courtesy of goals from Hugo Rodallega and Tom Cleverley, substitute Steven Fletcher prodding in a late reply for Wanderers.
West Ham had moved off the foot of the table earlier in the day with a 3-1 win at Fulham but McCarthy insisted that was not playing on his players' mind.
"It wasn't for me, although I can't speak for individuals," McCarthy said. "I think it is the goals we have conceded which determines the performance, not what has gone on before."
The home side had two penalty appeals turned down in the opening 45 minutes, one of which McCarthy felt was a certain spot-kick.
"There is one on Stephen Ward which is an absolute stone-waller but we haven't had one yet, so why bother?" McCarthy said, before joking: "I might not even designate a penalty taker, because it doesn't seem like we are going to get one."
