How's you blood pressure? We're off for a lie-down in a dark room.
Another day at the World Cup, another day dripping in drama.
And it's not over yet.

Brazil are already assured of a place in the last 16, but who will join them?
Second-placed Switzerland must beat Serbia to guarantee their progress, while a point would be enough if Cameroon fail to beat Brazil.
Serbia and Cameroon both need to win their respective games to keep alive their qualification hopes.
There will be high expectations after how the last few nights have gone!
It really has been an incredible conclusion to the group stages.
Thankfully, there's still more to come...
