A breakaway goal by Stefan Kießling in the 85th minute gave Leverkusen a 1–0 upset victory. Leverkusen manager Michael Skibbe praised Adler's "world-class saves". He stopped Schalke's record of 13 games unbeaten, Stuttgart's record of five games unbeaten and Hamburger SV four-game winning spree with a saved penalty kick against Rafael van der Vaart.

In the following years, Adler continued to be the first choice goalkeeper until newly signed Bernd Leno took his place due to injuries. He had made 37 appearances in the 2008–09 season, 33 appearances in 2009–10 season, and 44 appearances in the 2010–11 season.
