The Junior Boks kicked off their campaign with a solid 30-22 triumph over England last Friday, and while the team are happy with the winning start, they are less satisfied with a few aspects of their play.

The promising flyhalf was at the heart of South Africa's attacking moves in their opening game, setting up the first of five team tries and playing an influential hand in several other attacking moves against the powerful England outfit.

Mngomezulu said they are far more settled now that they have one tournament game behind them.

“Now we all know what it's like playing at this level and how small the margins are,” he said, calling for a strong mentality in their second game against Ireland.

“We didn’t play too well but we won by eight points, and we are happy to take that.

“We know what's required of us to do well against Ireland and we are training as if we've lost (our first game). That hunger and desire (to eliminate mistakes) are very evident in our training.”

Mngomezulu expects the wounded Irish to come out firing on all cylinders on Wednesday night, after they lost their opening clash to France by 42-21.

“They must be disappointed with their result against France because they won all their games in the Six Nations, so they would want to rectify matters against us,” said the Junior Bok captain.

“Therefore, we are putting in all the preparations to make sure we are physically and mentally ready to handle them.

The match against Ireland on Wednesday kicks off at 20:00.
