Frankfurt conceded three first-half goals to go down 4-2 to Maccabi Tel Aviv, but they know that a win against Bordeaux will be enough to see them through.
"Against Maccabi Tel-Aviv we went missing for one half, but we have had two totally different games since then and I can assure you that tomorrow we'll play for 90 minutes," he told UEFA.com.
"It is always important to have good results. In the games against Schalke and Mainz I did not see a bad team. We feel better and better. That's important on a psychological level - our performance against Schalke boosted us."
Frankfurt lead Group F by two points from Maccabi.
