Answer
The match in question refers to football legend Alfreð Finnbogason's first and only FIFA World Cup goal—scored against Nigeria on June 22, 2018, at Volgograd Arena in Russia during the 2018 FIFA World Cup. This historical moment marked Iceland's debut in the global tournament, clinching them a 2-0 victory over Nigeria and etching Alfreð's name in Icelandic footballing history.
