Krasimir Balakov has resigned as head coach of Bulgaria four days on from the 6-0 Euro 2020 qualifying loss to England that was marred by racist abuse.
The Bulgarian Football Union (BFU) confirmed Balakov's departure following a meeting of its executive committee on Friday.
In a statement, the BFU attributed the 53-year-old's resignation to substandard performances.
