"If you are an international player and you come to South Africa, you must show up. I want to find out what Sales' quality is, what is the quality of the guy?," Khanye asked on iDiski TV.
"Sundowns have been lately playing a different style, going wide to do crosses to find him in the box. The guy must move off the ball and set himself free so that his teammates can find him.
"But what I see every time is that when the ball arrives in the box, it can't find him."
The former dribbling wizard has also claimed that Mngqithi's team will be ordinary should Lucas Ribeiro Costa get injured.
"Let me tell you, if Ribeiro can get injured, any team will be able to beat Mamelodi Sundowns," said the Daveyton resident.
"We have to be honest, Sundowns lacked creativity, there was no sense of urgency, they were not good."
