McCarthy is relishing the clash with Villa and the chance to lock horns with Villa boss Martin O'Neill.
He said: "Martin has dome a great job wherever he has been. Villa are chasing the fourth spot and we are trying to stay out of the bottom there. We are all wanting points for something.
"There is a disparity of experience and ability, the way the clubs are, so we are the underdogs
"But we will give them a hell of a game though. I don't mind being the underdog. It gives me more pleasure when I win."
