Two of Ireland's sporting greats came head to head in the ring recently...sort of. 

As part of a campaign for Toyota Ireland, the two sporting heavyweights discussed what drives them, and the commitments that they have to make to their chosen sports. 

Obviously, being driven is a prerequisite to reaching that highest level, and they both got to experience a little bit of each other's world, which for O'Connell involved slapping on the gloves and stepping in to the ring with Katie.
