"I know well about his skills and I know how outstanding he is," Krejic said.
He noted the need to account for South Africa's collective attacking depth.
"I know there are many other great players, so I won't prepare just for him.
We should be careful not to let several players with excellent skills demonstrate their strengths in offensive situations," Krejic said.
The match will feature American referee Tori Penso, the first American woman to officiate a World Cup match.
"I haven't experienced a female referee, but I don't think it's a problem," Krejic said.
He expressed full confidence in the officiating crew.
"I don't think it matters whether it's a man or a woman. What matters is how well you do.
I hope the referees will see the game successfully," Krejic said.
The Czech captain thanked fans for their support.
"Thank you for the fans' support.
I believe you will receive the support of all the fans here, their families, and people back home.
