Bafana Bafana reached the Round of 32 for the first time after edging South Korea 1-0 at Monterrey Stadium.
Tshepang Moremi made an instant impact from the bench, setting up Thapelo Maseko for the decisive goal in the 63rd minute.
With confidence high, Mofokeng insists the squad remains fully focused on progressing as far as possible in the tournament.“We will fight to go as far as possible,” he told FIFA.com.
“We truly believe in our ability to achieve this; we will trust in God and give everything we have to get where we want to be.
“International football is the pinnacle, and as a national team player, you have to evolve constantly.
“Continuous improvement is essential, both as a player and as a person.
“You must learn from past mistakes to sharpen up for the next match; failing to do so only leads to defeat. We grew into the tournament game by game, and that is what matters most in football.”
South Africa's next challenge comes against co-hosts Canada in the Round of 32 on June 28 in Los Angeles.
