Ireland will be happy with the win, but they won't be happy with the performance and the way they started the game.
In the first half they were not up to scratch and I thought they looked incredibly nervous.
But they seemed to get more into it in the second half and were far more clinical.
Ronan O'Gara is not known for his pace but he did very well to break away in the lead-up to his try.
His kicking in the first half was very ordinary, but suddenly he was stroking the ball in the second half like he does time after time for Munster.
It would have been a serious blow for Ireland to have had the Grand Slam dream dashed on the rocks in the first game.
Next week against France at Croke Park is going to be extraordinary, and the week after against England will be history in the making.
It was a tremendous game of rugby, with great intensity and pace.
But the difference was the experience of the Irish midfield.
When the opportunities came, they took them, that was the difference.
Ireland were just more clinical.
I was surprised Ireland didn't dominate more up front given the experience of their front five.
I thought Paul O'Connell struggled and there didn't seem to be much leadership there.
They had one try gifted to them and two were well worked, but a win is a win.
Given the losses in their backline I thought Wales did reasonably well.
But they will be disappointed with the result because they were in with a good chance of victory after an hour.
