Travel back to Bergamo after Game

Hello there. Im vistiting the Big game tonight from Bergamo with a Friend. Our Hotel is in the middle of bergamo. Our Problem is that as good as i can See on the Internet the Last Train/Bus Takig us to bergamo is at 23:15 at Milano Certosa. So we have to leave early, or is there any kind of Special transportation or train/bus at match days? Besides a taxi because they are very expensive. Maybe some of you have the Same Problem and can help us ))

Thanks for ur help
