Melbourne Victory have parted ways with formation coach Ernie Merrick.
Victory announced the controversial decision at a media conference earlier today.
Merrick guided the Victory to A-League titles in 2007 and 2009.
The 57-year-old was the last original coach remaining in the A-League, having held the job since the club and competition's formation in 2005.
Melbourne's new chairman Anthony De Pietro defended the decision to make the change in the midst of the Champions League campaign.
"Our club sets extremely high standards and we are disappointed with the results of the recent A-League season and also our start to the Champions League campaign," Di Pietro said.
"Our intent is to continue to be the benchmark club in the A-League. We wish to be successful in Asia and believe this decision will assist in taking us to that level."
Victory youth team coach Mehmet Durakovic has been named interim coach and will take charge of Tuesday night's Champions League game against Jeju United.
