Rory Best stresses the need for Ireland to be switched on from the start

"We've got to make sure we don't start this game tomorrow cold, the way we did against Wales."

Ireland cannot afford to be "caught cold" again in the scrum in Saturday's RBS 6 Nations battle with France in Paris, according to Rory Best.

Captain Best has challenged Ireland's pack to iron out the kinks that allowed Wales to dominate the early set-piece exchanges in last weekend's 16-16 draw in Dublin.
