Nearly 60 per cent of tickets at Signal Iduna Park have already been reserved for the 2010-11 campaign.
"This number is an incredible credit of trust," Hans-Joachim Watzke, the chairman of the Dortmund managerial board told the club's official website. "But it also proves how much our fans identify with this young, enthusiastic team and the footballing philosophy involved in it.
"I'm sure that in the new season our fans will again be the deciding factor for one or two points."
With a capacity of 81,264, Dortmund's Signal Iduna Park is the largest stadium in Germany. Season ticket sales at Dortmund have eclipsed those sold at every other domestic club; Schalke are second with 43,190 sales, and Bayern Munich are third with 37,600.
Dortmund will be encouraged by their sales ahead of this Sunday's Bundesliga opener against Leverkusen, which is likely to draw a capacity crowd.
