We haven't played our best rugby yet, says Ireland coach Farrell

PARIS : Ireland coach Andy Farrell said his team have not played their best rugby yet despite booking their place in the quarter-finals with a fourth pool win of the tournament on Saturday.

The Irish ruthlessly took their chances in the 36-14 win over Scotland to set up a last-eight meeting with three-times champions New Zealand back at Stade de France next weekend.

"I don't think and neither does the team think that we have played our best rugby," Farrell said. "We know where we want to go and what we want to achieve.

"Will we ever get there? I don't know. But it's days like next week that are coming where we need to find out a bit more about ourselves and these lads are more than willing to do that."

Ireland, who have never won a knockout match at a World Cup, dismantled a Scottish side also looking to advance to the knockout stages, scoring early and scoring often to extend their winning streak to 17 straight games.

They had to get through a period of sustained pressure from the Scots after their first try, however, and Farrell thought the way the held firm then struck back at the other end was the key to the match.

"When you see how we were clinical and add how we were defending, it is a shot in the arm for us and a hammer blow for the other team," Farrell said.

There were a few injuries to concern Farrell, however, with wingers Mack Hansen and James Lowe forced off the pitch and lock James Ryan needing attention.

"Mack went off with a HIA (head injury assessment) and felt his calf straight away so we got him off," he said. "James Ryan has a bit of a knock on his wrist that we need to assess more, so we will see how he is.

"James Lowe got a bang in the eye, it shut and he couldn't see much, his vision was coming back
