Cape Town - Orlando Pirates coach Eric Tinkler is expecting AC Leopards pull out all the stops in their CAF Confederation Cup Group B clash at Orlando Stadium.
Pirates currently top the group, alongside Zamalek, on nine points from four games, and would secure their spot in the semi-finals of the competition with a win this weekend.
However, their Congolese opponents are not yet out of contention and could keep their own hopes of a last-four place alive if they beat the Buccaneers.
"This is an all or nothing game for Leopards," Tinkler told the Pirates website.
"They come to Jo'burg knowing that nothing less than a win will be sufficient.
"It is vitally important that we are disciplined defensively and ensure that we don't concede goals.
"When they do open up we need to punish them the same way we punished CS Sfaxien, that doesn't change.
"We need to play with intelligence, we know we need only one point but that doesn't mean we are going to sit back."
The Buccaneers are facing somewhat of an injury crisis heading into the game, with goalkeeper Brighton Mhlongo joining the likes of Ntsikelelo Nyauza on the physio table recently.
"Obviously we want all our best players available but [some injuries were] expected due to the fact that we have had the two seasons overlapping and the team has not had an end of season break.
"We are going to get injuries but fortunately for us with the exception of Brighton Mhlongo who has a major injury, everyone else who has been out has been minor and not too serious."
Kick-off is at 18:00 on Saturday, August 22.
