The 22-year-old is keeping his head down amidst the extra attention.
"I am focused on the work and that is all I do. I just focus on it and we'll see where all this takes me," said Tau.
"Now I've got people who make sure that I stay grounded. So I'm surrounded by a lot of people but there are a lot of things to do.
"Also my coach [Mosimane] is hard and he expects a lot from me. He demands a lot and it is always nice to have a coach like that. He always helps me to improve, so I'm just grateful."
Meanwhile, Tau says he misses former Sundowns teammate Keagan Dolly.
The attackers reunited in Bafana's victory at Moses Mabhida Stadium, with man of the match Dolly laying on the pass for Tau's clinical finish on the angle.
Dolly traded Downs for French Ligue One outfit Montpellier in January.
"I miss him [Dolly] a bit because he's a good player. I miss him, even the team misses him," said Tau, who was naturally delighted with his strike against the Wild Dogs.
"I'm happy that I scored and the team won, good pass from Keagan, like always. But I'm just so happy that we won."
