We've had a few results of this stature and we'll have some more as well. Japan have had a bit of a jab on the chin today and Costa Rica have kept their World Cup alive.

Japan's fans are at it again. Despite losing to Costa Rica, many have stayed behind to clear up litter in the stands.

A bit of a shock. What does that result say about Germany?

Just that one moment from Fuller changed the game. We thought Japan should win this game quite comfortably based on the form book but they were poor. They really struggled.
What a win for Costa Rica. They had to waste time and get energy back into the legs. They looked so much more organised today and made it that much more difficult for Japan.

Look at what this result means to the players of Costa Rica.
They end a seven-match winless run at the World Cup (W0-D4-L3, matches decided by a penalty shootout are classed as a draw).
Their last World Cup victories dated back to the 2014 group stage: against Uruguay (3-1) and Italy (1-0) respectively.

Wayne Ellis: Even if Germany lose tonight, they’ll probably only need to beat Costa Rica to qualify. Huge missed opportunity from Japan.
Count Ford: What we are seeing is the complete folly of judging teams based on one game/result. Any team at this World Cup, excluding Qatar, has got here because on their day they are capable of winning important matches.

This was always a great group. With Spain and Germany in the same group it was the proverbial group of death - and it is living up to expectations.

If Germany defeat Spain later (19:00 GMT), all four teams in Group E will be on three points with one round of games to play.

One of the worst games of football we've seen but we leave it with one of the greatest stories. Costa Rica coming back from losing 7-0 and not being fancied at all to seeing tears of joy from the players. Brilliant to watch.

Can you hear that roar? It's the whole of San Jose celebrating a famous World Cup win. It's approaching 4am in the capital of Costa Rica but no one is going to bed.

It's another big shock at the World Cup! Costa Rica only needed one chance. Keysher Fuller took his opportunity and it keeps their dream of reaching the last 16 alive.
After the 7-0 humbling to Spain, this is redemption. Look at what it means. Tears in eyes, the celebrations and the emotions spilling out from Costa Rica.

Japan have been poor from set pieces. They need some quality from the free-kick.
