At 22, Cossa appears to be one for the future for Chiefs, given his profile as a player who knows the culture of Amakhosi.
He helped the Soweto giants win the DStv Diski Challenge last season, having made his debut for the reserve side in 2023.
This was after he had been named the Amakhosi Under-19 Player of the Season the previous year.
At the end of the 2023/24 season, Cossa was honoured as the Chiefs DDC Players' Player of the Year.
