The 42-year-old believes Saturday's clash remains the most eagerly-anticipated of the Bundesliga calendar and is desperate to secure victory for the Schalke fans
The bitter rivals go head-to-head at Veltins Arena on Saturday with eight points separating the sides after just nine rounds of fixtures in the Bundesliga, although Schalke won both games last season 2-1.
But despite the gap between his side and Jurgen Klopp's charges, Keller is relishing the prospect of facing BVB once more in what he believes to be the most eagerly-anticipated game in the German calendar.
"There is no other game in Germany which electrifies the masses as much as this derby," the 42-year-old told a press conference.
"Every player knows what is at stake. A derby win means as much to the players as it does to the fans."
Schalke enter the match on the back of impressive Bundesliga wins over Augsburg and Eintracht Braunschweig, though they were humbled in midweek by Chelsea in the Champions League as they lost 3-0 in Gelsenkirchen.
