Pirates are showing fine form of late, as they outclassed Golden Arrows 4-0 in the Telkom Knockout quarter-finals last night, while they set up a Champions League Final date with seven-time continental champions Al Ahly this past weekend.
And De Sa insists Bucs have no intention of taking their foot off the pedal when they lock horns with Amakhosi at FNB Stadium.
"We have our focus on getting maximum points from that (derby) match. We will approach the match with the very same intensity we have been showing in all games," De Sa told his club's official website
"The guys are prepared mentally and otherwise, so there is not really much we can do in terms of inspiring them to play a good game on Saturday.
"We need the points in the League so, it will be war on Saturday no doubt about it.
"I have never seen the guys so motivated as they are at the moment.
"We will be cautious but we will definitely play to win the match, that is for sure," concluded the former Bidvest Wits tactician.
