Tau, 27, has been named in the Ahly squad by head coach Pitso Mosimane for their 2021/22 Egyptian Premier League opener after recovering from the hamstring injury that ruled him out from the Bafana Bafana squad last month.
Having earned a recall for the 34-man provisional squad named by Hugo Broos on Tuesday, the South Africa intentional will be aiming to make an immediate impact to prove his fitness for the final two 2022 FIFA World Cup qualifiers.
The club's marquee off-season signing from Premier League club Brighton and Hove Albion could come up against two familiar faces too when they face Ismaily this evening.
Justin Shonga and Benson Shilongo are both part of the squad for the opposition, having starred in the PSL with Orlando Pirates and Platinum Stars respectively.
The Namibia international has become an internal part of the squad since his R3.5-million switch from Smouha in December 2018 - with 17 goals and 10 assists in 73 games featuring in a role behind the striker or out wide.
Meanwhile, Shonga impressed during pre-season with a couple of goals and will be raring to go after seeing his career stall over the last two years in South Africa during ill-fated stints with TTM and Cape Town City.
The Club of the Century face three-time league champions at the iconic Borg El Arab Stadium this evening at 20h00.
