"He's been with the club for several seasons, and every footballer goes through an emotional phase," Niemach told KickOff.
"Before placing blame, we should consider whether he wants to stay at Sundowns or if he feels bored after achieving so much. Perhaps he needs a new challenge.
"Another possibility is that the coaching staff may feel he isn't fully present. But what I can say for sure is that Peter Shalulile is a finisher, and he can definitely add value to any club in the PSL. In South African football, we don't score enough goals," added the returned footballer who also turned out for Sundowns.
"The decision ultimately rests with the player. Without passion, there is no success. As a striker, you need that fire within you. If you lack passion, there's no point in playing; it’s like eating a meal without enjoying it.
"For Shalulile to perform at his best, he needs to feel that fire. It's not necessarily that the coach doesn't appreciate him; perhaps the team has evolved, and he finds himself in a different position. Sundowns has also improved tactically," Niemach continued.
"This doesn't imply a personal issue. The reality is that he will fit in at certain moments. We aspire to be the best on the continent, and for that, some tough decisions are required.
"I commend Shalulile for everything he has done for the club, he is part of the legacy that Sundowns is today."
