Eddie O'Sullivan looks likely to experiment against the Pacific Islanders this weekend but insists Lansdowne Road must be given a victorious send-off, to add to the wins over Australia and South Africa.

Successive wins over the two southern hemisphere sides have presented O'Sullivan with the opportunity to test out those players on the fringe of the first team who have a chance of making the World Cup squad.

O'Sullivan names his side tomorrow and has left little doubt they will be expected to complete a clean sweep of victories from the autumn series and close the curtain on Lansdowne Road with a win

The oldest international rugby stadium in the world will be hosting its final Test before beginning a massive redevelopment in January.

"There will be some changes. Other than Marcus Horan we have a clean bill of health. We'll pick the 22 from the 32 that we have at the moment," he said.

"There is a good bit of elbow room now after winning the first two games and we'll look at doing things differently against the Islanders.

"But I still want to win. I don't want to throw away the last Test at Lansdowne Road before the wrecking crew move in, so we want to leave on a good note.

"We have a lot of good stuff in the bank from the last two weeks and we have to analyse it and move.

"I'm happy we've produced two very good performances against different teams in different conditions. We have set a standard for ourselves.

That bit of elbow room may afford the chance to the likes of Stephen Ferris and Luke Fitzgerald to show what they can do on the international stage. Both impressed in the Ireland A defeat to Australia but O'Sullivan is wary of breaking up the winning mentality.

"It's the chicken-and-egg scenario - winning gives you confidence and confidence helps you win," he said today. "It's working well for us at the moment so we need to take it and move onto next week."

Ireland thumped South Africa by a record margin and also matched their previous highest victory over the Wallabies, results which have lifted the side to third in the world rankings.

John Connolly, the Australia coach, rated them as the best team in Europe and they will be red-hot favourites to win next year's RBS 6 Nations.

But while O'Sullivan has attempted to play down their stunning progress, he admits this month's success will stand them in good stead when they renew battle with the rest of Europe.

"What you sow in the autumn you reap in the spring. This time last year things weren't going well for us," he said. "We were struggling, getting a good hiding off New Zealand and getting beaten by Australia. We lost the last quarter against the Wallabies badly.

"At that stage we were sowing a lot of seeds in terms of personnel and the type of game we were trying to play.

"This time last year we couldn't play our current type of game if we wanted to because we didn't have the confidence, the personnel in place or the skill set needed."

The Islanders, who are made up of players from Fiji, Samoa and Tonga, have lost both matches on tour to Wales and Scotland but remain dangerous opponents.

Ireland defence coach Graham Steadman said: "I watched them against Scotland and they were very good in the second half.

"We'll approach the game slightly differently but the main objective is to keep them out like we did against Australia and there's no reason why we can't."
