"The male from Chelsea stands to double his money if Simon Cowell’s latest superstar justifies her position as the red-hot odds-on favourite at 4/11 to be named as this year’s winner on Sunday night."
Err...what?... He put a bet on at 4/11 so "stands to double his money"? For his £20000 he'll win just under £7300 (total back £27300). So... yeah. Not exactly double. Or even half of double.
This is what is known as trying to "buy money". It's incredibly risky, and I hope he gets burned
