As has been the case so often over the last 18 months, as soon as Hamburg's season seemed to be taking off, they were brought crashing back down to earth with a defeat.
However, Fink has been warmed by what he has seen in training this week and expects that Hannover defeat to be a mere blip rather than the start of a worrying trend.
"They've looked really motivated," he said. "Now we need to carry what we have been doing in training over into tomorrow's [Saturday] game.
"I am really motivated too, but I can't play, I can just set the tone."
That tone should be three points to lift Hamburg back into the top six, although Fink has warned that opponents Greuther Furth are better than their league position suggests.
"Furth have nothing to lose," he said. "Their draw against Leverkusen suggested things are looking up for them, but we have got to demolish this optimism."
Indeed Furth, including their caretaker coach Ludwig Preis, can only gain from their trip north.
A draw against Leverkusen in Preis' first game in charge has not only fuelled hopes that the Bavarians can mount a rally against relegation, but also given Preis a chance of claiming the job on a regular basis.
"The way we played against Leverkusen gives us hope," said Preis. "We now want to repeat that performance.
"We want to frustrate Hamburg a little."
Edgar Prib will not make the trip north due to a thigh strain while Sercan Sararer is a doubt.
