Cape Town - Manchester United legend Gary Neville and ex-Liverpool star Jamie Carragher were on top form when the pair aired their different views over defenders in the modern game.
There are fewer, if any, more famous old boys or "one club men" than Gary Neville and Jamie Carragher and tension is bound to rise when you put the pair in a room.
Neville, who made over 400 appearances for United, and Carragher, who made over 500 appearances for Liverpool, were both on the panel for Sky Sports edition of Monday Night Football.
When the topic of full backs versus wing backs came up, the pair were not afraid to disagree.
Carragher feels that the requirements of the modern game for a full back means there is very little needed from such a player to adjust to playing as a wing back while the former club captain of Manchester United disagreed.
Neville used his personal experience of playing in both roles to argue his point. He is adamant that the technical and physical demands of a wing back means that a specialist player was required to take up that position.
Neville appeared to gain the upper hand on the debate when he ended by poking fun at Carragher. Neville hinted that he had evidence to suggest the former Liverpool star could not play as a wing back.
