The teams played to a 1-1 draw in Tshwane last month and will decide the tie at Harry Gwala Stadium on Saturday night (20h15). The victor will battle either Cape Town City or champions Bidvest Wits for tournament honours.
Maritzburg, who have never reached a major final, enter the contest with confidence having seen off kings of Africa Mamelodi Sundowns in the last-eight, while they top the Premiership standings with six points from two games.
Weidlich is mindful Fadlu Davids' outfit can not afford to let their focus slip against the Nedbank Cup holders.
“I don’t think we should look much at what happened two weeks ago, I think we should just focus on this game. Yes, we scored the away goal that that we needed, but we’re not thinking about that,” he told his club's website.
“We just want to take what we have been working on in training into the game and put up the kind of performance we know we can.
“For most of us, and since I have been in this country, we have not been in this situation in the semi-final leg, having a good chance to make the final. But we are not there yet, this cup is all about winning, we must go all out to try and reach the final.”
The German believes the modestly assembled Team of Choice are growing as a force.
“We all know there are bigger brands in the league, but I think the way we have been playing this season has attracted many people to the team,” he said. “Now we have to try and keep it up, to keep those standards, whether at home or away.
“The style of football, we have been showing other teams in the league, that ‘hey, this Maritzburg might be a small name, but on the pitch we are all chasing the same ball’. Any team that thinks it’s going to be easy against us will be in for a surprise.”
