Ireland must start their World Cup Pool D match against Georgia on Saturday in much the same vein as Argentina did, flanker David Wallace said.

"We'll have to hold on to the ball, try and break them down a lot more rather than trying to score tries from anywhere and everywhere," Wallace said.

"Georgia looked very physical and hard to break down," he was quoted as saying on the Irish union Web site http://www.irfu.ie.

Argentina were made to work hard for their 33-3 victory over the Georgians in Lyon on Tuesday. They led only 6-3 at halftime and scored their fourth try for a bonus point in the last minute.

Ireland will have to improve from their 32-17 win over Namibia in their pool opener last weekend if they are to score another bonus point and go top of the pool before they meet hosts France in Paris on Sept. 21.

Wallace, in his first World Cup, was also impressed by Georgia's ability to run with the ball.

"Their number 10 looked a good passer and was able to spin the ball wide.

"They showed some good skills in the backs, so are capable of playing an open game too," said Wallace, who recovered from an ankle injury to play his first international since March when he lined up against Namibia.

"They'll have taken great confidence from their first match and that will make them more dangerous against us," added the 31-year-old openside flanker.

Wallace said Georgia's game against Argentina was as the Irish had expected with the fitness of the Pumas carrying them through in the end.

He added, however, that "if the Georgians had got lucky in the match, they might have been able to hold out for a little bit longer.

"We would have preferred it had Argentina not got the bonus point from the match. Argentina will be in contention for winning the pool," Wallace said.

Argentina, who upset France in the tournament's opening match in Paris, top the pool table. Ireland meet the Pumas at the Parc des Princes in Paris on Sept. 30.

"It's not going to be an easy pool, that's for sure. Georgia have shown they haven't come here to make up the numbers, they won't lie down and be beaten. It means we'll have to work hard in every game," Wallace added.
