Day dreaming doesn't do it for O'Driscoll

But while that ambition is driving O'Driscoll and co onwards and upwards as they look to establish themselves as arguably the most successful squad in the history of the competition, the star centre insists that only focussing on the job in hand will see them home against their Irish rivals.

"I've found myself day dreaming a little bit and thinking about how great it would be to win three from four but that does nothing for you," said O'Driscoll, who has recovered from minor knee surgery to take his place in the Leinster line up.

"That's not going to win it for you. You just have to think about the job at hand and each moment in the game and your involvement. If we're all collectively thinking that way then hopefully we'll be there towards the end of the game.

"You can't worry about the prize. I'm a big believer in thinking about the process and not the prize.

"All you can do, all that we're in control of, is training well and hopefully playing well this weekend. You've got to let the result take care of itself. You can get caught up thinking about it. We haven't won anything yet."
