Ireland powered past Six Nations rivals Scotland 27-3 to put themselves in the box seat to reach the quarter-finals at the Rugby World Cup on Sunday.

Three push-over tries in the first half did the damage before wing Andrew Conway grabbed a fourth after the break to secure a bonus-point win, with games to come against Japan, Russia and Samoa in Pool A.

"We started really well – we were positive, we wanted to attack," said Ireland captain Rory Best.

"Obviously with the conditions in the second half it became a bit more of an arm-wrestle but we know how good a team they are and we're delighted with that win."
