The former Black Leopards and Baroka star played under four different coaches at The Village but only made an impression on Giovanni Solinas.
Ntshangase has been released by the Soweto giants and Moloi feels the midfielder should have been taught how to close down a space and be one step ahead of an attacker instead of being expected to be involved in tackles.
"Football is modern, you have to do defensive duties," Moloi tells snl24.com/kickoff.
"It also depends on what defensive duties you want him to do, but he has to do defensive duties and as a coach you have to create exercises that will teach him how to do defensive duties. I mean mina I used to fight with my teammates when they told me to mark. But it was because it was translated wrong.
"I always used to think marking meant sliding, winning the ball. Marking doesn't mean you must come out with bruises like Bernard Lushozi. That is not marking. Marking means to be goal-side to prevent your opponent from receiving the ball freely, and to toe-poke the ball out of your opponent's control.
"That's what South Americans taught me. They said to me, 'If he doesn't receive the ball free, he feels that there's somebody harassing him when he receives the ball... that's marking.' But all the time before I went to South America I thought marking meant to come out of tackles bruised like Lucas Radebe and win the ball. And that is not me.
"But they said, 'Be goal-side, prevent him from scoring, from turning, from attacking. When they pass to him he must pass it back. He mustn't run at your teammates. He mustn't run into a goalscoring position freely and be able to control the ball and end up scoring. You must be there next to him and disturb him.'
"Marking means to just disturb your opponent so he can't do as he wishes freely, that's all. Now that's why I'm saying I don't know how it was translated to Ntshangase to say what is marking. That's how they told me in South America and I got game time. I did my defensive duties. Marking doesn't mean now Ntshangase must win balls, slide and do tackles, no!
"Perfect example, Surprise Moriri. Surprise was very good at anticipating a ball so it doesn't reach his opponent. He used to slide before the ball reaches you and then got up and ran with it. He was very good at that. A lot of ball-playing players can learn from the way Surprise did it. He never ran after an attacker but he played for Sundowns. I think Ntshangase can mark if he is taught what I've just told you."
