Losing from Union Berlin have close chance for Freiburg can finish on top fourth place and have close dreaming with champion league ticket next season. I think Freiburg almost can finish on top fourth after inconsistent from Leipzig but little mistake have close chance for Freiburg. Last match Bayern Leverkusen is not easy for defeating by Freiburg beside with Leipzig get easy team against with Arminia Bielefeld, exactly last champion league ticket will be on Leipzig hands.
Purely theoretically, it can be assumed that Arminia will want to show himself at home in the last match and, from fundamental considerations, will beat Leipzig, and taking into account the fact that Bayer can no longer rise above or fall below, Freiburg has a chance to win. But such a scenario looks unlikely, probably a multi-bet on this event will have odds like 1 to 30.
