The Hungarian giants won Game One in front of their own fans, only to fall 52-39 in Poland in Game Two.
"In Krakow we started the game well, but later we missed a few easy shots and after we were shaky on offense," MKB coach Norbert Székely said, before trying to take the pressure off his team.
"You know, this is a very young team, and it could easily happen," he said. "Otherwise we are mentally strong, so these players are ready to step up and forget this bad game quickly.
"Krakow has a very good team, but if we play our game with aggressive defense and offense, then we have good chance of stepping into the best eight teams in Europe.
"Our basic aim was to reach the Eighth-Finals, so this next step would be a great success for this young team. In this season, we have worked hard for this possibility and now we have to realize it."
Australian Kathleen Macleod admits Friday's setback at Wisla was a huge disappointment.
"I was sad after the game in Krakow because a lot of Hungarian fans followed us to Poland, and we couldn't make them happy," she said.
"I hope on Wednesday evening we can make it up to them and celebrate a big success together."
MKB only hit 25.6% (11 of 43) of their shots inside the arc, 20% (two of 10) beyond it and 11 of 18 (61.1%) at the free throw line.
Katalin Honti, who missed all six of her shots from the floor in that low-scoring contest, said: "I believe in our success. In Krakow we had a very bad day. We couldn't shoot. I'm sure we will show our better face tomorrow and win the game."
