“We made a few mistakes [in the last Derby]. We didn’t really play good football on the day," he admitted.
"However, we have since worked hard on fixing those mistakes and we are positive of getting a result on Saturday.
“We don’t want to miss out on an opportunity to reach a cup final, although we will take it step-by-step."
With the clash being staged in front of their avid KwaZulu Natal-based supporters, Castro is expecting an exciting atmosphere throughout the 90 minutes.
“It’s great that we have taken this game to Durban. It’s already sold out, which means that there will be a fantastic atmosphere at Moses Mabhida Stadium," he noted.
"We love our supporters in KZN. We just need to take our talent onto the field and go out and play.”
