The 2005 RBS 6 Nations promises to reach a thrilling climax on Saturday when Ireland meet Wales at the Millennium Stadium in a potentially epic encounter where several different outcomes are possible.

Victory for Mike Ruddocks side would hand Wales a first Grand Slam in 27 years while should Ireland win by at least 13 points - and France fail to beat Italy by a minimum of 42 - the Irish will be crowned champions.

But OSullivan believes his team must concentrate only on triumphing in Cardiff so they retain their Triple Crown - and consider anything else a bonus.

You have to be careful about trying to win games by a certain total - the most important thing is to win the match first. That would give us a Triple Crown. Then well see what happens after that, he said.

Its important to close the deal first - it would be foolish to approach it any other way. Im sure this game will go down to the wire so we must prepare for it with the right mindset, and that means just trying to win.

Its been a funny championship this year and predictions that it would be close have proved correct. There are so many different ways it could finish on Saturday. Three teams could win it and there is also a Grand Slam and Triple Crown to be won.

OSullivan insists Saturdays 26-19 defeat to France at Lansdowne Road has already been consigned to history and revealed a lesson had been learnt from the way Englands World Cup-winning side overcame major setbacks.

The lads have bounced back already. They were very down on Sunday morning but training went really well (on Tuesday). The great challenge for any competitive athlete is how you deal with failure, he said.

It didnt come off against France and there are two ways of dealing with that. You learn from it or suffer from it. I like to look at what England did in this situation. They lost four Grand Slam games in a row.

They said theyd get better because of it and they did - they went on to win a Grand Slam and the World Cup.

You can go backwards or forwards in this situation - you cant stand still.

Were all disappointed about it but theres no reason to be too down on ourselves, especially given whats left to play for on Saturday.''
