Donncha: O’Brien will have plate full

DONNCHA O’Callaghan is predicting an epic duel between opensides Sean O’Brien and Sam Warburton at Wellington Regional Stadium tomorrow.

O’Brien is a wrecking ball who always breaks the first tackle while Warburton is a fetcher who dominates the breakdown.

Both players have emerged as stars of the World Cup and O’Callaghan insists they are at the very top of their game.
