Tau scored the only goal of the game to lead Sundowns to a 1-0 win over Maritzburg United in Tshwane on Wednesday evening.
The fleet-footed playmaker credited the coach and his teammates for a hard-fought victory.
"Thank you so much. I think we fought very hard. It wasn't an easy game but we did our work. We're happy we got the results," Tau told SuperSport TV.
"They are playing a system that is very difficult to defend [against] but we knew when to attack and when to defend which is something good. We did our analysis very well, credit to the coach and the guys. We did really well.
"I think it's always good to win our catch-up games. Last season we didn't do that, so we're happy that this season we're doing that. Masandawana are happy today."
