Zwane has managed to garner 101 points for Usuthu from 63 games since moving to Durban, which is more than Chiefs have managed over the same period and from the same number of games.
In the 63 matches since Zwane joined AmaZulu, Chiefs have managed 94 points, seven fewer than Usuthu.
They have won the Nedbank Cup in that time, but there might be questions asked as to whether Amakhosi should have persevered with their former winger.
In fact, only Mamelodi Sundowns (155 points from 64 games) and Orlando Pirates (140 points from 62 games) have managed more points than Zwane at AmaZulu since he arrived at the club.
It is a remarkable statistic that shows how he has stabilised the team and led them to sixth, fourth and currently third in the Betway Premiership.
This campaign, AmaZulu have taken 16 points from a possible 21, with five wins, a draw and a defeat to Sundowns.
