Tau has been the star performer for Sundowns this season, scoring 13 goals in total, at least one for every competition, for the Brazilians.
The 24-year-old also finished joint top goalscorer in the Absa Premiership with Rodney Ramagalela of Polokwane City.
Danish side Midtjylland were also said to be keen on the Bafana Bafana player in January, although they did not table an offer for him.
Sundowns are reportedly looking for a fee of about R45 million for their star player.
It’s unclear if any of the aforementioned clubs will be willing to match the Brazilians’ asking price.
