Irish captain Rory Best said that Ireland will have to improve upon their performance if they are to win in the Millennium Stadium next week and deny Wales a Grand Slam.

Speaking after Ireland’s impressive win over France, Best said that a similar showing in Wales next week will not be good enough.

"We’ve got to be better than the way we played today. We played well and we know there’s more to come, but to go to the Millennium Stadium and win with everything at stake is going to take a massive effort," he told RTÉ Sport.

Despite stating that there was still work to do, Best insisted that the performance was Ireland’s best of the Six Nations.  

"We were really, really miserly with the ball, we didn’t give them anything easy and we put a lot of pressure on them. I think that we played a lot closer to how we can play, which is pleasing."

Ireland coasted into a 26-0 lead on Sunday before a lull allowed France to register two tries before the final whistle, but Best was keen not to blame the raft of substitutions Joe Schmidt made as the game entered the closing stages. 

"That’s not an excuse for us. We work really hard and we put a lot of emphasis on the bench. I actually think that the bench came on and lifted the game and if we could have scored in that series of scrums that would have been a big lift for us."

Playing in what is likely to be his final Irish game at the Aviva Stadium, Best said that he was "absolutely delighted" with the send-off.
