Wolves striker Chris Iwelumo is happy to fight for his place.
Iwelumo has struggled to hold down a regular spot but is full of praise for the straightforward approach of McCarthy.
He said: "The gaffer is as honest as they come. He tells it as it is. The way we play, the way we work, is all about what he puts to us and how he wants us to play.
"First and foremost you've got to work your socks off and then all that passing, the quality and magic on the ball, comes a close second.
"That is the way it is always going to be."
