The national teams of Hungary and Romania are longtime rivals, as the two countries are neighbours and had numerous conflicts through history.

After the Greek win against Romania, many Hungarians celebrated it in social media and in Budapest too, because their biggest opponent got eliminated from the World Cup.

[5] A part of the Hungarian fans went in Romania for the game with shirts showing the message "Hungary on Tour - Gypsyland II, Bucharest 2014.10.11.

[citation needed] According to Gazeta Sporturilor, Romanian ultras were let to the Stadium without properly being searched[7] and, before the match between Hungary and Romania, threw firecrackers, lighters and steam grenades at the Hungarian fans, who responded by throwing broken chairs at the Romanian ultras.

According to Adevărul, the events were not far away from a cancellation of the match, that would have resulted in a 0–3 score for Hungary, because the Romanian fans used pyrotechnical tools in a huge amount.

Scottish referee William Collum was forced to dish out 12 yellow cards during the match, while police sprayed tear gas at fans in the stands.

Both sets of supporters created a deafening roar throughout the game, letting off flares and firecrackers, to the dismay of onlooking police.

These incidents occurred during the first league matches Diósgyőr–Újpest 2–1, Honvéd–Puskás Akadémia 0–0, Vasas–MTK 0–1 and Videoton–Debrecen 1–0, the fined clubs were Újpest, Honvéd, Videoton, Debrecen, MTK and Diósgyőr.

A few days before the match, there was a campaign by a section of Hungarians to show superiority during the rejection of the Romanian National Anthem, which was named "Ne fütyüld ki a román himnuszt!"

During the game, Hungarian fans booed Romania's national anthem with turning on their backs, showing obscene gestures, whistling all the time and lit flares and torches inside the stadium.
