A run of eight straight defeats has seen the Swabians slump to the brink of the bottom three.
Schneider is still clinging on to his job, but failure to beat a side who are just three points behind them and at the foot of the table would all but certainly signal the second change on the Stuttgart bench this season.
"It's been an emotional week," Schneider said. "Also in view of the fans coming to training to show us their support.
"I think it's going to be a special game."
Stuttgart forward Cacau is convinced not only that his side will turn the corner this Saturday, but that Schneider is the right man to guide them away from relegation.
"We're not thinking about what might happen if we lose," he said to SWR television. "We're going into the game with confidence and optimism.
"Of course it's hard after eight defeats, but I'm convinced we will get out of there, with Schneider."
Braunschweig have already sealed the fate of one coach this season, Hamburg's Bert van Marwijk being fired after a 4-2 defeat in a similar relegation battle, but Eintracht's Karim Bellarabi says that is not their objective.
"We need to focus on ourselves," he said on his club's website. "Only they know what situation they are in and what's positive and negative there. We have to concentrate on giving it all we've got, regardless of what's going on there.
"We need to play courageously, like in recent weeks. Stuttgart have 19 points and we've got 16 and if we win, we're right in there."
