Since the Absa Premiership ended on May 27, SuperSport have contested two CAF Confederation Cup games while Pirates have been left to play friendlies matches.
Matsatsantsa, the defending Ke Yona champions, also head into Saturday's Moses Mabhida Stadium showpiece as favourites, based on league form where SuperSport finished fifth and Pirates 11th.
“Pirates haven't done well in terms of their log standing this past season but this is a different game, it’s a cup game,” Tembo told reporters on Thursday.
“[But] I don't think that we under any pressure to defend the trophy, though winning the cup back-to-back it is something that we want to achieve.
“It’s not going to be an easy game and they have improved a lot since the coach [Kjell Jonevret] came in. They have played with a little bit more structure and more discipline.”
Tembo says his side will rather focus on their own game-plan.
“I think the most important thing for us is to really focus on our own game and try to be the better team on the day. Pirates haven't been playing competitive games and we have [in the Confederation Cup],” he said.
SuperSport defeated Pirates 3-2 in the Nedbank Cup final played in Polokwane in 2016.
