Belgium has crushed Tunisia 5-2, with forward and captain Eden Hazard and striker Romelu Lukaku both scoring doubles.
Hazard scored the first goal in the 6th minute when Belgium was granted a penalty, while Lukaku doubled the team's lead in the 16th minute when he rifled his shot into the bottom corner following an assist by Dris Mertens.
Dylan Bronn pulled one back for Tunisia just two minutes after with a wonderful header from Wahbi Khazri's free kick.
During stoppage time, Lukaku scored his second goal and his fourth of the tournament, thus becoming one of the footballers with the most scored goals at the 2018 World Cup alongside Cristiano Ronaldo. Chelsea star Hazard has also scored a double in the 51th minute of the dynamic match.
Belgium's Michy Batshuayi and Tunisia's Wahbi Khazri scored the last two goals after the 90th minute of the epic match.
Hazard was named the man of the match, FIFA said on Saturday via the tournament's official Twitter account.
Belgium, alongside England, is poised to make it to the playoffs after winning its first game of the tournament.
