The result put them on top of the group with 15 points from seven games, with an unassailable seven point lead over third-placed Montenegro, who have two games left to play.

Hungary took the lead through Martin Adam’s close-range header following a free kick from captain Dominik Szoboszlai from the right after 10 minutes.

Marco Rossi’s squad seemed close to doubling their lead, but on Bulgaria’s first chance, Spas Delev scored with a shot into the top right corner to make it 1-1 in the 24th minute.

The hosts were dealt a blow before halftime when they were reduced to nine men after red cards for Valentin Antov and Ilia Gruev, but the VAR intervened to overturn the latter and keep hopes of a Bulgarian comeback alive.

Hungary were also reduced to 10 men early in the second half when Milos Kerkez was sent off and suffered a major setback in the 78th minute as Kiril Despodov scored with a penalty to give Bulgaria a 2-1 lead.

As Hungary got close to suffer their first defeat in a year, Petkov headed in his own goal from a corner seven minutes into stoppage time to send his team into their third consecutive European championship finals.
