O'Driscoll eyes big performance

Brian O'Driscoll has told Ireland's new arrivals the heroics against South Africa must be reproduced in Sunday's showdown with Australia.

Ireland made a blistering start to their autumn schedule courtesy of a 32-15 victory over the Springboks, a result that has given head coach Eddie O'Sullivan room to experiment. Ulster duo Isaac Boss and Bryan Young will make their full Test debuts, while Geordan Murphy is handed the number 15 jersey. Denis Hickie completes the changes, with Andrew Trimble ruled out through injury.

"The changes show we have real depth. The four lads have slotted in and the team doesn't look like it's been weakened in any shape or form," said O'Driscoll. "We set ourselves a good standard last weekend and I've spoken about not dipping below that bar."

He added: "There's real pressure on the lads who are coming in - and those who have hung onto their places - to re-enact the whole thing.

"Following last weekend there is balance to strike between keeping a lid on our enthusiasm and encouraging the guys to do more of the same."
