The Austrian has guided the Tykes to just one win in all competitions during his short time at the helm at Oakwell, with the Reds currently 13 games without a win.
Saturday's 2-1 defeat at Bristol City - a seventh-successive loss - has forced the hand of the club hierarchy who will now be searching for a third new manager in the space of 12 months.
We took a look at how Schopp's win percentage stacks up against the previous nine Barnsley managers, only including men who have taken charge of 10 or more games at the club.
