Nothing is impossible when it comes to sport bets, we have been proven wrong so many times in the past when we bet on the sure bets and they lost, I can remember the day israel Adesanya lost that UFC fight, many people lost money that day because they believed he will win.

There are many times where Barcelona have been leading because they are just that good but there are few times where they lost to those who we once thought was impossible.

The best way to take risks on such games is risking small money like OP did and this doesn't mean it will keep happening, that's why they have biggest odds over others.
