Derby have sacked Phillip Cocu with the Rams sat rock-bottom of the Championship.
A wretched run of form has seen the Pride Park club pick up just one win from their opening 11 matches to leave them stuck in the relegation zone.
Cocu saw his side score just five goals in the league this term before being given his marching orders along with coaches Chris van der Weerden and Twan Scheepers.
Manchester United and England record goal scorer Wayne Rooney is among a group of interim coaches, along with ex-Newcastle and Ireland goalkeeper Shay Given, Liam Rosenior and Justin Walker.
Derby said in a statement: "Derby County Football Club and manager Phillip Cocu have parted company by mutual agreement with immediate effect.
"Assistant Manager Chris van der Weerden and Specialist First Team Coach Twan Scheepers have also left the club by mutual agreement.
"Cocu was appointed as Derby’s manager in the summer of 2019 and oversaw 65 matches in total across all competitions.
"The club would like to place on record its appreciation for the way Phillip and his staff conducted themselves in what were some extremely challenging situations during his tenure.
"Phillip and his staff helped develop and establish a considerable number of Academy players in to the first team squad and Phillip made significant financial contributions and personal efforts towards the club’s community projects during the COVID-19 pandemic, which the club are extremely grateful for.
"Derby County wishes to thank Phillip, Chris and Twan for their hard work and dedication over the last 16 months and wish them every success in their future careers.
"The club will provide further updates when appropriate and will be making no further comment in the meantime."
Derby are currently in the midst of a takeover and a new manager is likely to be appointed after the club's owners are confirmed.
