Jamie Roberts admits Wales will have to up their game when they take on Ireland in their next RBS 6 Nations clash.
The Cardiff Blues centre was arguably Wales' best player in Saturday's 24-16 win over Italy in Rome and was singled out for praise by coach Warren Gatland.
Roberts produced his most accomplished display since recovering from a long-term wrist injury that sidelined him for the autumn Tests.
And the 24-year-old, one of the British and Irish Lions stars during their Test series against South Africa in 2009, believes he is on the way back towards recapturing his best form.
Roberts said: "That was the most carries I've had in a game for a while.
"I was pretty disappointed with my own performance against England a few weeks ago. I wasn't proactive enough and didn't get the ball in my hands.
"I love carrying the ball - that's what I am about - and I think I am on the way to getting back to where I want to be.
"It feels so much better as a player when you get to carry, and that is what I love to do. The gainline is what I am about, and I certainly did that against Italy."
Of concern to Roberts though, was Wales' poor discipline. They conceded 15 penalties to Italy's five, with any similar statistic likely to cost them dear when Ireland arrive in Cardiff on March 12.
He added: "I was pleased with our performance, but frustrated at times. It was our discipline more than anything which let us down.
"We gave away too many penalties, some of them silly, to put ourselves under pressure.
"We conceded 15, which wasn't clever really. If we do that against Ireland we are going to be punished because we probably won't win the game.
"It could have cost us against Italy, and it is crucial we improve our discipline.
"We scored two good tries (by Morgan Stoddart and Sam Warburton), but didn't push on. Italy got their tries by pouncing on our errors. Their first came when we shipped ball along our line we shouldn't have done.
"Their second came when we tried to throw the ball around. We let them back in, and we certainly won't be able to do that against Ireland.
"We definitely need to raise our standards against Ireland. They've certainly got the players to punish us."
