"I think it [the problem at Chiefs] is more than scoring, it is defending, it is structure. It's a discipline," Tau said as per KickOff.
"You look at the last goal they conceded [against Polokwane City]. It's the 88th minute, the goal kick was taken by [Sibongiseni] Mthethwa, who passes to [Yusuf] Maart.
"At no point do you see the centre-backs appearing anywhere? That's a lack of discipline because you need to keep the structure of the team," added the former Amakhosi skipper.
"The fact that your two centre-backs are going to be in the build-up but then when the break happens, none of them are actually there.
"So I think there is a lot. Defensively, I think they are found wanting."
