Zulu joined Amakhosi from Maritzburg United, where he previously worked with Chiefs head coach Steve Komphela, while Zimbabwe international Hadebe was snapped up from Chicken Inn FC.
Both players reported for the first day of pre-season training in Soweto today, although it marks the second time Hadebe has trained with Chiefs, having failed to impress during trials this time last year.
“We have been working throughout the break to negotiate and finalise some of these deals,” Motaung is quoted as saying on Chiefs’ official website.
“We need to make sure that coach Steve and his new assistant have a strong team that will compete fiercely in the new season.
“We welcome the duo to our stable and hope that they live up to expectations and make our supporters happy,” added Motaung.
“We have been monitoring them and we really felt they could help improve our squad.”
The Glamour Boys also revealed they "will make further announcements regarding player signings and promotions in due course".
