But McCarthy insists is he not expecting an easy ride from Paul Sturrock's men.
"Don't even suggest Plymouth is an easy game," he told the club's official website. "Look at it this way. There's a greyhound going through a field and he sees a rabbit. The rabbit starts running. The greyhound fancies a bit of snap but the rabbit fancies his life. Who runs the hardest? The rabbit, absolutely. That's been my view on life.
"If you're fighting to survive, like Plymouth are in this league, and they're on about sacking the manager, changing players around - it's supposedly desperation stakes there.
"People fighting for survival are not easy to play against. We're going to have to play equally as well as we did on Sunday and it might be a harder game than Cardiff, just like Norwich was, or Doncaster."
