Petar Hubchev was manager at the start of the qualifiers but was replaced by Krasimir Balakov after drawing the opening two Group A games 1-1 against Montenegro and Kosovo. A key member of the legendary Bulgarian side that reached the semi-finals of the 1994 FIFA World Cup, Balakov failed to mirror his achievements as a player with the national team, as defeats against the Czech Republic, Kosovo and two heavy losses against England followed between June and October 2019. Only a 0-0 draw against Montenegro disrupted the unenviable run of straight defeats.
Balakov was replaced by current manager Georgi Dermendzhiev for the final match of the campaign, and a solitary goal from Vasil Bozhikov earned their only victory as the Czech Republic were defeated 1-0 in Sofia. Prior to EURO 2020 qualifying, Bulgaria had enjoyed a relatively successful campaign in the inaugural UEFA Nations League, earning promotion from League C to League B under the management of Hubchev, as they finished two points behind group winners Norway, a team they defeated 1-0 in September 2018 through a goal from Radoslav Vasilev. The side will now look to return to form in the second edition of this competition after a difficult calendar year.
