Ireland are in no mood to be involved in another upset when they meet Russia in a Rugby World Cup pool match in Rotorua on Sunday afternoon.
Ireland unexpectedly beat Australia last Saturday 15-6.
But talk in the Irish camp this week has been all about not underestimating the Russians.
Prop Cian Healy says Ireland have the utmost respect for Russia.
"If you go out talking down a side, you're going to be giving away silly tries," he said.
Victory for Ireland will move them back to the top of Pool C.
Russia have lost both their opening matches at their first World Cup, but managed to score three tries against Italy after a close match with the United States.
"Russia and Ireland have different goals in the competition," said coach Nikolay Nerush.
"Ireland are aiming at the highest results, while we are just getting experience. Our task on Sunday is to play worthily."
