A 1-0 victory over Olympiacos ensured Schalke's progress from the group stage of the Champions League with a match to spare, although there is no time to revel in the glory, according to midfielder Julian Draxler.
"Of course we were all pleased and relieved to have made it through, but there is no time to celebrate," he said.
"We enjoyed the moment for a short while, but then focused on the future again - we have the next tough challenge ahead with Frankfurt."
The Royal Blues can now focus all of their efforts on domestic affairs and not even an energy-sapping few weeks will weaken them, claims Draxler.
"Of course the last few weeks have been hard, but that's part of the game when you are in three competitions," he said on his club's website.
"But we will make it through to the winter break, no worries.
"We are all professionals and there will be times when one or two of us lack a bit of freshness, but that is why our squad is set up the way it is.
"Our coach will send the right team onto the pitch."
Draxler also expects Stevens to keep the motivation high for what he predicts will be a tough game.
"Frankfurt are certainly the surprise of the season," he said. "They play very good attacking football and, with Alexander Meier, they have a potent player among their ranks.
"We are warned, not only of him, but also of the other players. Frankfurt are very versatile and that makes them hard to fathom."
Despite being level on points with Schalke, Frankfurt coach Armin Veh says there is little else in common between the two sides.
"It was no coincidence that Schalke were third last season and that they are into the last 16 of the Champions League," he said.
"We cannot compare ourselves to them for sure."
