KIEV, Nov 4 (Reuters) - Dynamo Kiev coach Jozef Sabo, who has been plagued by cardiac problems, has gone on permanent leave and is to be replaced by his assistant Oleg Luzhniy, the club announced on its website on Sunday.
Sabo took over as Dynamo coach in September after Anatoly Demyanenko stepped down in response to the club's poor performance in the Champions League.
He had coached the club through the 1990s and again in 2004-2005 and had also played for Dynamo, Ukraine's most celebrated club, in the 1960s.
Luzhniy, a former Dynamo captain, joined the club's staff earlier this year after finishing his playing career at Arsenal.
Dynamo Kiev are without a point from three games in the Champions League and face Manchester United at Old Trafford on Wednesday. The club lies third in the Ukrainian league behind arch rivals Shakhtar Donetsk and Dnipro Dnipropetrovsk.
