Since the global showpiece the national team has managed to generate great interest in their local games.
Pitso Mosimane's men attracted 40 000 to the FNB Stadium when they took on Ghana in an international friendly on August 11 and then on September 436 744 flocked to the Mbombela Stadium in Nelspruit.
And the Amakhosi defender tells Football365.co.za the good form of the national team is connected with the incredible support they have received.
"The support has been a big boost, because even when I call guys like Siphiwe Tshabalala, Reneilwe Letsholonyane and Itumeleng Khune while they are in camp you can tell that the motivation is based on the response they have been getting from the nation at the Bafana games since the World Cup," he said.
"I think that's been a big plus for the country and we can always hope that the nation will always be behind the national team, whether they are doing good or doing bad.
"We've got to adopt an approach of being loyal to our national team. Let's rally behind the guys at all times."
Tau, who has eight Bafana caps to his name, also expressed his delight at the way the team has performed.
"I'm very happy with the progress the country has made and I think hosting the World Cup has also contributed to that," he added.
"I know we were knocked out in the first round, but I think the way we played has paved a way for an improvement. The fact that we were willing to compete, the way we fought at that level, has had a positive bearing on the way we are playing now.
"I'm more impressed with the understanding that the team seems to be sharing... there is a foundation and you can tell we have continued where Carlos Alberto Parreira left off. It augurs well for the country going forward.
"So credit to the team and all those who have put their weight behind the coach, Pitso Mosimane and the players," concluded Tau.
