Eredivisie strugglers Go Ahead Eagles have fired coach Foeke Booy following their home defeat to Vitesse Arnhem on Saturday.
Booy had already announced his intention to leave at the end of the season but a run of five successive losses has seen the club replace him with Alfons Groenendijk, a statement said.
Go Ahead Eagles have won only twice since the winter break and scored four times in their last 11 matches.
Booy joined the Deventer club in 2013 after they won promotion but they sit second from bottom with 23 points from 28 matches.
