Barnsley have sacked manager Danny Wilson and assistant Chris Hutchings.
The club revealed their disappointment with recent performances and results, pointing out Wilson had one of the largest wage budgets in the division.
The Reds sit 17th in League One following Tuesday’s defeat to Fleetwood Town, their sixth defeat in nine matches. They have lost each of their last six away games.
Barnsley do hoewever sit equidistant from the top six and bottom four, seven points away from each.
Academy chief Mark Burton has been appointed caretaker manager and will be assisted by senior development coach Paul Heckingbottom as the Reds prepare for the trip to struggling Crawley this weekend.
The club statement read: “The Club would like to place on record its thanks for Danny’s work-ethic and determination during his time with the Club and the support Chris provided Danny with since he joined the Club in March 2014.
“Danny joined the Club at a very difficult time which was a testament to his character and affection for the Club – all the while demonstrating the utmost professionalism during his time with the Club.
“Danny will always be welcome back at Oakwell.
“The success he brought during his initial period with the Club is unrivalled and the Club will be forever grateful for his achievements.
“However, recent performances and results have been concerning, considering the Club currently boasts the fifth highest wage bill in League One in addition to a fourth highest equity donation by our owner.
“Meanwhile, our current League position of 17th is in stark contrast to an average home gate of sixth-best in the division.
“Whilst the Club acknowledges there has been a large turnover of players, the league position is still unacceptable considering all of the above.
“Barnsley Football Club asks all supporters to please get behind Mark Burton and Paul Heckingbottom on Saturday as we seek three valuable points to propel the side up the league table.
“The Club can assure fans that a suitable candidate will be selected and in place at the earliest opportunity.
“While media speculation will be constant during the search, the Club will aim to select the correct candidate in private and will make a further announcement as and when it is appropriate.”
