A lengthy review by the video assistant referee (VAR) preceded confirmation of Japan's second goal against Spain on Thursday, as the Samurai Blue secured yet another shock win at the Qatar World Cup following last week's victory against powerhouse Germany.
Japan came from behind to beat the Spaniards 2-1, qualifying for the knockout stage as the winners of Group E.
In the 51st minute, Ritsu Doan, the scorer of Japan's equalizer, fired a cross into the penalty area that was just beyond the reach of striker Daizen Maeda. But winger Kaoru Mitoma managed to keep the ball alive, deftly sending it across the face of the goal where a switched-on Ao Tanaka slipped past a defender and knocked the ball into the net.
