World Cup 2018: 3 reasons why Belgium managed a stunning comeback win against Japan

#2 A change of system

Japan's threat forced Roberto Martinez to tinker his formation

Roberto Martinez's 3-4-3 system has probably been discussed more than the recent Donald Trump - Kim Jong-Un meet. The system does not seem to favour the players at his disposal and the Japanese exploited it to the fullest. The fullbacks on whom Martinez's entire system revolves had a poor game.

But with a double substitution after going 2-0 down, Belgium applied a fluid system drifting between 4-4-2 and a 4-4-3. This helped the Belgians in regaining control of the midfield as they found a way to beat the Japanese press. Lukaku and Fellaini helped with the physicality whereas Kevin De Bruyne was given more freedom to surge ahead.

A couple of positive changes and a shift in strategy led Belgium to extend their stay in Russia. It remains to be seen whether this is the last time we will see Belgium's 3-4-3 formation in the World Cup. Martinez must dump it to have a solid midfield and to provide freedom to his MVP - Kevin De Bruyne.
