While McCarthy may not play that style at club level, he believes that he has the quality to shine as a keeper for the national team.
Southgate prioritises playing out from the back, with the manager expecting keepers to be comfortable with the ball as well.
"It's a part of my game where I feel comfortable," he said to the Daily Echo.
"Obviously a lot of managers now like the play to start from the back. It's an area that I've worked on in my game for a while now, so it'd be an area I'd be comfortable in doing.
"I think the way that football is going now, it's a massive part of the game so you'e got to be able to do that."
