Matt: Japan need to keep the foot on the pedal and keep on attacking. Belgium are vulnerable now. Major major upset boiling up.
David: Roberto is off to the Job Centre tomorrow, will Southgate be in the queue behind him?
Manpreet: This World Cup has been magnificent, but Japan need to hold on, the job is not done yet
Belgium 0-2 Japan
What a start to the half. Mind blowing stuff. A reminder that Japan have never won a knockout game at the World Cup.
Reminder that Belgium are ranked THREE in the world.
Mind you, Germany are one...

Wooooshhh....

Are Belgium a team? Because they need to show their spirit now. It's going to take a monumental effort to get back into this game. The two Japanese centre-backs have been magnificent and they're going to have to be for the rest of the game.
Belgium 0-2 Japan
Is this shaping up to be the biggest shock of them all at this World Cup?
Goodness me. Russia 2018, you are really spoiling us. Pass the Ferrero Rocher.
Yannick Carrasco leans back and spanks one wide. He's been poor.

Southgate is a genius. Deliberately lost to Belgium to avoid the mighty Japan!
Darren
It's official - all bets are off at this World Cup. I'm sticking with my Japan v Swiss final shout though...
Belgium 0-2 Japan
Belgium have won just two of their 20 World Cup games in which they have conceded the first goal.

Such clean football by Japan. It's hit like an arrow and a top goalkeeper is beaten from distance. It has power and precision and it stays hit. Wonderful strike.

Takashi Inui
Well, well, well...
Pick that one out! Japan have a two-goal lead and it's an absolute belter! It's gone 4am in Japan but they will be rocking now. Shinji Kagawa tees up Takashi Inui, he's about 25 yards out, nobody goes to close him down and he shifts it to his right and then clips it into the far corner. Luka Modric-style, that.
Great goal, GREAT STORY!

Jay: Belgium are doing their best England impression
Andy: Win the group they said! Play Japan they said! Give yourself an easy knock out game they said
Javel: At least now we know we'll see BEL score twice!

Vertonghen should win it but it's a wonderful strike by Haraguchi. Japan really are playing at the top of their game tonight.
Belgium 0-1 Japan
Are we on for a cracker of a second half? Dries Mertens finds Eden Hazard inside the area and the Chelsea man wafts a wand of a right boot at it, clipping the post and away!
Almost an instant, immaculate response.
As it stands, Japan will play Brazil...

Genki Haraguchi
The Japan v Switzerland final remains ON!
Another goal for the underdog at this World Cup and it's brilliantly taken! A mistake from Jan Vertonghen though, he fails to cut out a good ball forwards, the ball skimming under his studs, Sunday league style.
It opens up for Genki Haraguchi, he runs into the area, hesistates just for a moment and looks like he's going to play it square, but then flashes a shot past Thibaut Courtois, who was foxed by the delay.

We hear Japanese tennis player Kei Nishikori is watching the game with former world number one Kim Clijsters...who is from...you guessed it...Belgium.

Slow and steady start to the half as on 5 live we discuss what makes a lobster and what makes a crayfish, something about a local delicacy in Rostov.
Belgium 0-0 Japan
Japan still haven't won a World Cup knockout match. Can they do it in Rostov?

Japan playing so well, following the example Wales set when they beat Belgium at the Euros. Well drilled, organised, high pressing and catching them on the break. Still think Belgium have the edge but Japan have been outstanding so far.

How does Belgium's multilingual team communicate?
Sources say the players speak neither Dutch nor French but English in the changing room, to avoid the perception of favouring one language over another.
They also speak English on the pitch, much to the surprise of many in the UK press during their game with England on Thursday night.
A majority of Belgians are Dutch-speakers who live in the Flemish north. Most of the rest speak French, and there is a small German-speaking community.
This divide can be seen in the mother tongues of the Belgian national team's star players.
Manchester City's playmaker Kevin De Bruyne is a Dutch-speaker from Ghent in the Flemish region, while Chelsea attacker Eden Hazard is a French-speaker from the Walloon region.
