The club confirmed the 43-year-old Serbian's departure, which had looked inevitable after The Reds' recent poor run.
"After the defeat in the Bulgarian Cup final, coach Milos Kruscic declared his desire to vacate the post," CSKA said."He took responsibility for the failure and offered his resignation, which was accepted by the club's owners." Former Yugoslavia defender Kruscic took charge at CSKA in October, replacing his compatriot Ljupko Petrovic.Once-mighty CSKA, hoping to clinch a Europa League berth, are third in the Bulgarian league standings with three games remaining.
