Captain Johnny Sexton believes Ireland's previous World Cup struggles will not impact on the team's performances at this year's tournament.

Sexton, 38, will start Saturday's pool opener against Romania despite not having played in nearly six months because of injury and suspension.

"We always get tarnished that weve havent got past a quarter-final but Ive some amazing memories at World Cups," said Sexton, who will be playing in the tournament for a fourth time.

"Obviously a few of them, theyve ended badly but were very much looking forward. Were not carrying any of that baggage with us."
