According to Ertugral, the son of Amakhosi's top dog ran straight to the Ajax mentor to show him an inappropriate gesture after he had netted the first goal.
This action, which the Turkish-born boss feels warranted a straight red card, has left Ertugral hot under the collar and he is now likely to take the matter further.
He told Football365.co.za: "I am going to take the matter further. I will be writing a letter to the federation about the matter.
"He should have got a straight red card. I have never been humiliated like that in my entire life of football," said the irate coach.
Ertugral said he was now going to speak to Kaizer Motaung about the behaviour of his son.
He continued: "I am so close to the Motaungs. They are a very humble family I don't know about that boy.
"I am going to speak to his father and discuss it with him further. Kaizer Jr does not deserve to play for Chiefs. He is carrying such a big name but behaves in that manner. He was the first culprit when I was at Chiefs," he said.
Neither Chiefs' Thebe Mohatle nor PSL media officer Altaaf Kazi were available for comment.
