The night of the unwelcome guest.

If you've ever thrown a good house party, you'll know the telltale signs. You've spent ages meticulously planning. You've invited the coolest, most popular kids, stocked the fridge to its very limits and spent an extraordinary amount of money on things you would never normally buy. Like breadsticks, houmous and those little cheesey squares.

You try and make sure everyone's having a good time, the music is just right, the lighting spot on. And then, just when the night is reaching its peak, you hope that it all pays off with some big moves on the dancefloor. Alright, your mum's conservatory.

But there's always one guy who outstays his welcome. Making too much noise, drinking too much, getting in the way. If you're not careful they take all the glory and you're left with nothing but angry neighbours, suspicious stains on the carpets and a very expensive repair bill.

Well tonight, Brazil's month-long party hits the big stage. The hosts have put on a great show and are now just one game away from the final. One game away from a shot at greatness.

But who invited the Germans? Can Brazil shift one last unwelcome guest and get them in a taxi home? Or will Joachim Low's side be marching on to the Maracana?

Time for the big tunes. Time for the big one...
