IRELAND SKIPPER BRIAN Brian O’Driscoll admits his side have a lot of work to do improve on this morning’s opening World Cup performance.

Declan Kidney’s men won unconvincingly, 22-10, against Eddie O’Sullivan’s USA in New Plymouth.

Tommy Bowe scored a try in each half, while hooker Rory Best also got over but the United States had the final say when centre Paul Emerick ran in a late intercept try.

Leinster centre O’Driscoll told ITV: “We didn’t play well, we had to fight for our win. I suppose we got the win but we have a hell of a lot to improve on.

“We couldn’t get any continuity. We were a little bit loose. It’s good to get 80 minutes under your belt now we’ve got a big challenge at the weekend against Australia.

“We can work on bad aspects of our game during the week.”

Declan Kidney, meanwhile, said he was “delighted with the win”.

“Another big one – that is why you get into it,” he told TV reporters, “It’s a six-day turnaround to Eden Park (v Australia).”
