"It's too much high-speed runs and the altitude [is high]. But yeah. That's one thing that we must do, we need to run extra hard. We need to give, a little bit more effort.
“I recently watched the game of Germany versus Curacao, 7-1 and yeah the intensity was very high, it was high-level, it was top, top, top,” added the former SuperSport United prospect.
"We want to improve as much as it’s a big tournament and there’s very big teams participating but we must showcase our talents. We must not let down the people of South Africa."
