"Though he is a good striker, I'm concerned about his movements. He doesn't create enough space for his teammates to find him," he told SNL24.
"That's why they struggle to find him, which affects his ability to score goals. His movements around the box are not good.
"He often hides from the ball, and most of the time, he positions himself at the far post or stands at the penalty spot. Those positions are for overlapping teammates and oncoming attacking midfielders.
"As a result, he is going to struggle to score goals. A striker should always be the first one to react to second balls.
"For me, I think they should let Ranga go because if Chiefs manage to find a new striker, especially now with Tashreeq Morris in the mix, I don’t think Ranga will play again.
"Every time Morris plays, there is a lot of movement up front, and there's no way they will play Ranga while keeping a fit Morris on the bench. Morris does things that Chivaviro can’t," Matsau concluded.
