With nine goals so far in Russia, Belgium are the World Cup's top-scoring team. The win saw Belgium continue their 22-match unbeaten run - the longest in their history - and reflected the class and depth of this hugely-talented side.
Dries Mertens has warned Belgium against the perils of complacency as they prepare to face Japan here Monday with one eye on a possible quarter-final showdown with Brazil.
Nobody doubted the ability of Roberto Martinez's side, but here was a true test of their resolve. "We were determined to disrupt a Belgium side at their best, but at the end we couldn't really match them".
It was end-to-end stuff for the final quarter of an hour. "His stats speak for themselves".
The Belgium squad consisted of ageing superstar and future Belgium manager Marc Wilmots, and future Bayern Munich star Daniel Van Buyten, while the Japanese squad consisted of Feyenoord star Shinji Ono, and legendary Asian player and the only player in Japan to be named in the Federation Internationale de Football Association 100 list, Hidetoshi Nakata. The last country to do so was West Germany, in their quarter-final against England at Mexico 1970. Even their goalkeeper Eiji Kawashima now plays for Metz in France, and had previously featured for Lierse SK and Standard de Liege in the Belgian top-flight league.
The victor of the Belgium-England match would take Group G and while there were strong arguments as to why perhaps winning for either side wasn't important due to future draws, Belgium got the job done as it won 1-0.Adrian Januzaj scored the game's lone goal on a blast in the 51st minute.
Brazil v Costa Rica
Costa replaced Chelsea winger Willian at the start of the second period and there was immediately a greater urgency from Brazil . Thiago Silva admits he was "saddened" by Neymar's outburst at him during Brazil's 2-0 World Cup win over Costa Rica on Friday.
Keisuke Honda became the first Japanese player to score at three World Cups when he netted a vital equaliser in the 2-2 draw against Senegal, which ultimately proved decisive in Japan's quest to qualify for the last 16. Manager Akira Nishino had his team expertly set up to effectively pressure Belgium's three-man backline of Toby Alderweireld, Jan Vertonghen and Vincent Kompany.
Japan used a 4-4-2 formation in their last group match against Poland and lost.
Nobody expected Japan to pose a serious threat to the Belgian Red Devils, but Takashi Inui added a second goal for Japan just four minutes later. The Japanese will target attacking through the wings where Gaku Shibasaki will play a vital role. "We would like to play Japan-like".
Belgium have not kept a clean sheet in their 12 World Cup knockout-round matches, shipping 28 goals. I think this contest gets to three goals and perhaps a couple more, especially with Lukaku back in the lineup.
Both the teams had faced each other just seven months ago in a friendly in Bruges as part of their World Cup preparation.
Lukaku, who was marked, left it for Chadli to tap home and cap Belgium's stunning win right before the final whistle. Teams such as Brazil or Mexico could await them in the quarterfinals, while France or Uruguay loom further down the line.
