Spurs have not played since a 3-1 loss to Blackpool on February 22, but have not been idle in the days following that shock result. Harry Redknapp's team have just returned from a warm-weather training camp in Dubai, something that the Wolves manager thinks could work either for or against them as they look to continue a run of strong results at home this season.
"You don't know how it affects teams," said McCarthy. "It can have an adverse affect, not playing for quite a while, but it can also have a galvanising effect, with players spending a bit of time together. They could come here and be brilliant, they've got the potential to be that."
He added: "But then we've got the potential to beat anybody at Molineux."
Meanwhile, McCarthy is refusing to rush Michael Kightly back into the first team to aid their relegation battle, despite the injury-plagued winger playing 45 minutes of a reserve game on Thursday.
Kightly, whose last match was in November 2009, has been blighted with ankle and knee injuries which have seen his comeback constantly delayed.
But after the winger played in the 3-3 reserve team draw against Manchester United without any setbacks, McCarthy is hoping that his injury hell is at an end.
"He was excellent and he's been training really well," he said.
"He had 45 minutes, feels great, and I'm really pleased with his progress.
"He'll come back when he's ready. I'm not rushing him."
