RB Leipzig's victory over Freiburg on Saturday, coupled with Hertha Berlin's defeat to Mainz, confirmed the eastern club's place in next season's UEFA Champions League qualifying round at the very least.

It represents a quite astonishing achievement for Ralph Hasenhüttl's team, considering this is their maiden season in the Bundesliga following promotion from the second tier at the end of the 2015/16 campaign.
