Atletico Madrid stunned Barcelona on Sunday night, inflicting the champions' first domestic La Liga defeat of the season thanks to a well earned 2-1 win.

Unsurprisingly, Barca went into the encounter as strong favourites, yet goals from Simao and Diego Forlan brought their fabulous league run to a shuddering halt.

The game was the focus of our charity betting challenge, and as our data below shows, while the result may have been a surprise, the disparity between the odds offered by private and public operators was anything but.

We're sure you'll agree that it is both  quite amazing and galling how German punters, forced to bet with a state monopoly, are receiving almost 50% less profit on the same bet with the same stake,  compared to many of their European neighbours.
