The Munster forward will line-up at Twickenham for the RBS 6 Nations clash looking to help the Irish clinch a shock victory - and he reckons all the pressure is on Englands shoulders.

You never think youre going to reach 50 caps. But I suppose Ive been pretty fortunate in the way Ive had a good run in the team over the last four or five seasons. In that time the caps have started to mount up, he said.

Playing the world champions is a good way to mark your 50th cap. There isnt a whole lot of expectation on us because everyone is expecting England to win. Its a massive, massive game.

Foley is under no illusions over what it will take to defeat the World Cup winners in their own back yard - Ireland have triumphed at Twickenham just once in the last 22 years while England are unbeaten in a home Test since 1999.

But he is quick to point out that his verdict on Irelands chances is based on Englands strength on the pitch, not on records and statistics which will count for little when hostilities commence.

Well have to play the perfect match to win. We need to settle early and get into our rhythm. If England are going to score against us then we must make them work extremely hard for it, said the back-rower.

But what happened in the past is irrelevant. Its just a matter of going out and seeing who is the better side on the day. Hopefully we will implement what weve been working on all week and see if it works out for us.

Playing at Twickenham can be mission impossible if you go in with the wrong attitude. Its important that we get our heads right, go out, take them on and see what theyre made of. We can come out on top if we do that.
