Mashaba has been without a club ever since he parted ways with the Brazilians in 2017.
He has now been given him a chance to redeem himself as they look to further bolster their squad ahead of the 2018/19 season.
Chiefs caretaker coach Patrick Mabedi, previously hinted that the club was keen on bringing a left-back following the departures of Sibusiso Khumalo and Tsepo Masilela at the end of last term.
Meanwhile, Chiefs recently appointed Italian Giovanni Solinas as their new head coach, and it appears that his first order of business, will be to assess the 29-year-old.
“We have Mzi with us for training while the Technical Team have a look at him,” the Soweto giants team manager Bobby Motaung said in a statement issued by the club.
“We will see how it goes and a final decision on him will be made in due course,” he added.
Mashaba is a versatile player, who can play either as a winger or full-back.
“We are looking at bolstering the left side of our play,” he explained.
“We know what he can offer but he has been out of action for a while and with our new coach (Giovanni Solinas) also coming in, we want to make informed decisions before finalising anything,” he concluded.
If the Glamour Boys do sign Mashaba, it will certainly be a signal of intent by the club following a host of new signings as they look to bring back the glory days after three trophy barren seasons.
Mashaba could also potentially link up with former Brazilians teammates Khama Billiat and Leonardo Castro at the club if his trial proves successful.
His arrivals comes after Chiefs pulled out of the race to sign Mosa Lebusa from Ajax Cape Town.
Lebusa appears to be heading to Sundowns, who tabled a better offer to that of Chiefs.
