Shonga, a policeman by profession, joined Pirates on a three-year contract in September from Nkwazi FC, and went on to make his Buccaneers debut in a 2-2 draw with Polokwane City last weekend.
Allegations recently surfaced that he had also penned a deal with Mamelodi Sundowns, but the Brazilians are unlikely to go head-to-head with Bucs in a legal battle for the Chipolopolo striker.
Regardless of how his career pans out in the PSL, the 20-year-old has a job waiting for him in his homeland should he return.
"He is not entitled to any benefits from the police force but he has the chance to get his job back when he returns from Pirates," says a source.
"This is not the first time Pirates are in this situation. They did the same thing with the striker Mzwandile Mamba who used to play for Royal Leopards which is a police team in Swaziland, even though he ended up going back to Swaziland without kicking a ball in the PSL."
