Stadium Management SA (SMSA) said on Thursday it expected a sell-out for the annual one-off match between Orlando Pirates and Kaizer Chiefs on July 28.
At last year's inaugural game, SMSA said a little under 80 000 fans had turned up at the 94 000-seater stadium.
"SMSA is confident that this year's edition will be sold out," the stadium managers said in a statement.
"To cater for a capacity crowd and ensure the smooth running of the Carling Black Label Cup, SMSA is urging fans to arrive early and take full advantage of a host of parking and travel arrangements in place for match day."
The cup game boasts a unique format which allows fans to vote for the players they want in each team, and also allows spectators to make changes on the field during the match.
