Hyypia said he is confident that the players can put their 2-1 Europa League defeat to Benfica behind them and bounce back against Furth.
"We are by no means underestimating Furth," Bundesliga.de quotes him as saying. "A change of coach can always give a new impetus so this makes the task very dangerous.
"For me as a player it was after defeats that I worked harder and was at my best. The players can do the same on Sunday in Furth."
Leverkusen are third in the Bundesliga, just a point behind second-placed Borussia Dortmund.
