Their story in the last couple of years is insane.
13/14 - 2nd and promoted to Bundesliga for the first in club history
14/15 - 18th and relegated to 2. Liga. Fun Fact: They are to this day the last team other than Bayern, Dortmund und Leipzig to be top of the Bundesliga at the end of a matchday (4th Matchday).
15/16 - 18th and relegated to 3. Liga
16/17 - 18th and technically relegated to Regionalliga (4. Division), only stayed in 3. Liga because 1860 failed to get a license because of financial issues
17/18 - 2nd place and promoted to 2. Bundesliga
18/19 - 2nd place and promoted to Bundesliga
They changed managers 5 times in that period
