South Africa has claimed over 100 goals in their first two group stage fixtures against Barbados and Trinidad & Tobago, and still face Malawi on Tuesday and Fiji on Wednesday.
Coach Precious Mthembu’s shared her assessment of the team’s start to the tournament.
“I am really proud of the team; they really showed character. They were very consistent, defensively we held Trinidad under 20 goals," she noted.
"Our aim was not to score 100 goals; we were all about winning and what you saw on the board today took care of itself. While the confidence is high, we need to make sure that we maintain this level and be humbled in the process.
"I think here and there we had moments of relapse, and any strong opponent would punish us. These are some of the things we need to continue working on."
