O'Sullivan was delighted with the way his side performed

The win puts Ireland on four points and victories in their remaining games over Scotland and England would hand them the Triple Crown.

"We have to take one game at a time," O'Sullivan said.

"But it's great to be in a situation where we are the authors of our own destiny in the championship."

And O'Sullivan was pleased with the way his side bounced back from their defeat to France last time out.

"I'm very pleased with the performance. It was very solid and workmanlike," he added. "Any notions that Wales weren't going to play were blown away fairly early on.

"They got possession and held on to it. They ran us hard and made us work. They scored an early try which threw the gauntlet down at us but we responded very well.

"Over the 80 minutes we deserved to win the game and played the better rugby. The most pleasing aspect was our defence - we defended superbly."

It's still wide open and there for the taking for the team which puts their hand up Ireland skipper Brian O'Driscoll

Man-of-the-match Shane Horgan admitted Ireland had to overcome a shaky start to secure their win in Dublin.

Horgan, along with David Wallace and Peter Stringer, scored tries as Ireland secured an impressive win.

"There were a lot of nerves and Wales came out very strongly," said the Leinster winger.

"They were aggressive in the tackle and we did not get much first-phase ball. But we got more in the second half and played better rugby."

Irish skipper Brian O'Driscoll believed his side could be pleased with a job well done.

Wales reaction

"It was a performance that had been coming for a while and it does not shock me all that much," said O'Driscoll.

"When the pressure came on we produced the goods and we can take great satisfaction from that.

"It's still wide open and there for the taking for the team which puts their hand up.

"All you can do is play as well as you can. Thankfully we played well today. You can never look to win championships - you're silly to look beyond the next game."
