I don't know what Dortmund was thinking about why they let the result end in a draw. It can be seen from Dortmund's game that they didn't use all their strength to get a win, and you can also see that Heidenheim's last four matches also ended in a draw. Like this, many gamblers lose because they think it will be easy for Dortmund to win, but in the end, the result ends in a draw and makes the gamblers disappointed.
Oh damn , just have seen it right now and yes i lost my bet here also as i was really thinking that Dortmund will win that.
I am also disappointed from the result as Dortmund would be needed all the points , ok at least they havnt lost this match.
But as i said in my last post Heidenheim is always good for a surprise and if keep doing that i guess they will stay in the first german league.
