As you can see on the screenshot below, over £1 Million was traded on Arsenal at prices from 1.05 down to 1.01.
Thats not all, £6 was staked on Wigan at odds of 800/1, and over £100 was backed at odds of 350/1, just to list a couple.
With Arsenal leading 2-0 in the 79th minute, you wouldn’t have given Wigan a chance. The big layers just look to hoover up so-called ‘free money’ at low odds, hence the amount traded in the screen shot. The layer (layers) of 800/1 on Wigan, would have thought it was just money for old rope.
It just goes to show that there is no such thing as free money.
