Mako, alongside Thabiso Monyane, left Pirates together as the Sea Robbers let them go in a bid to create space for their expected new recruits.
The left-back spent seven seasons with the Buccaneers, but he faced injury challenges, and one of the biggest such setbacks was a knee ligament injury suffered in October 2023 that sidelined him for almost one year.
If he finally signs for Chiefs, that would mean more options for Nasreddine Nabi. The Tunisian coach mostly deployed Dillon Solomons and Bradley Cross and, at times, Zitha Kwinika when Reeve Frosler was injured.
Amakhosi had reportedly identified Fawaaz Basadien as their top left-back transfer target, but this is understood to have proved a difficult mission, as Stellenbosch FC were unwilling to let go of one of their prized assets.
Riaan Hanamub of AmaZulu had also been reported to be a target for Chiefs, but the Namibian has been offered a new contract by Usuthu, technically making him unavailable.
