Bayern Munich enter this season as favourites under new manager Pep Guardiola after sweeping up the treble last season and reinforcing their team over the summer with the likes of Mario Gotze and Thiago Alcantara.
The Bavarians looked impressive in their pre-season friendlies, racking up more than 60 goals with dominant performances including 15-1 and 13-0 friendly wins.
Dortmund served up a warning that Bayern's quest to defend their treble will not be an easy one with a thrilling 4-2 win over them in the DFB-Supercup last Saturday at the Signal Iduna Park, and Sahin believes that the result will also remind the other teams that Bayern are not invincible.
"Bayern's preparations for the Supercup were great," Sahin told Bundesliga's official website, "They scored close to 60 goals in friendlies and cleaned up. That was really impressive and obviously the other clubs really respect that.
"However, we've laid down a marker for the Bundesliga. We've proven there's another way. I think that was in the interest of the entire league.
"We can be really pleased. In my eyes, we've capped off some really good groundwork by winning the Supercup. Bring on the season!"
Sahin also believes that the win is significant with new signingsPierre-Emerick Aubameyang and Sokratis Papastathopoulos playing significant roles.
"The game was important for our newcomers," the Turkey international enthused. "They've seen what sort of an atmosphere there is at Dortmund and have slotted in seamlessly.
"[Pierre-Emerick] Aubameyang introduced himself with an assist, while Papastathopoulos provided added stability towards the end of the game. All in all, it was a good day for us and the new boys."
