The Limpop outfit suffered a 2-1 defeat at the hands of Pirates on Saturday afternoon.
Nyirenda claims his side are not learning from the previous mistakes, which hurt them again.
“Like I said before the game, our mistakes are the same. We seem not to be getting it right at the back, we’re giving away silly goals. The first goal how do you give a player of [Vincent] Pule’s calibre all that space? You’re committing suicide.
“The second goal was just a give-away. The goalkeeper had a miscommunication with the defender. Those are school boy mistakes.
“Then look at our chances. We had more clear chances than them in the second half. In the second half we came looking good but all those chances we gave them away. We need to work on scoring chances and defending well.”
The Zambian born mentor indicated that he is not satisfied with the quality of players at his disposal.
“It’s frustrating when you know the problem and you try to work on it but it’s not coming. Then it means you don’t have the machinery.
“There’s nothing I can do now. These are players that we have we just have to work on them,” he said.
