Kiss: Devised the choke tackle

Defence guru Kiss devised the tackling technique that sees players, usually working in pairs, grab opponent and ball around chest height. The tacklers then work together to prevent the ball from being grounded, thus increasing the chances of being awarded the put in at the scrum.

The tactic has attracted plenty of attention since it was used to great effect in the 15-6 victory over Australia, but Kiss insists it is just one facet of Ireland's game.

"Other teams have already started copying it. England took it on and were speaking to me about it after the Six Nations," said Kiss.

"Some things you can't keep under cover for too long. Certainly some teams are starting to look at the technique in a certain way.

"Fortunately referees are looking at it in the context of the law and how it can be applied.

"We have a lot of tools in our box to use and we don't just rely on the choke tackle.

"That's the beauty of this side, we can put pressure on in different ways."

Ireland saw the best defensive record at the World Cup come to an end in the 62-12 victory over Russia.

Two second-half tries were leaked to the Pool C minnows, knocking the Irish down the defensive pecking order.

"We were in the position to have the best defence after round three. That isn't the case now, but it's still a good effort by the boys," said Kiss.

"The United States' try was an intercept and then there were the two against Russia.

"There are things to work on and this will make us hungry to improve, which is important.

"We're concerned when a point goes against us, particularly at set piece. We are usually very good at defending set pieces.

"But I'm not going to hang myself on it, you have to take your hat off to them. They had fast backs with sevens experience."
