Honestly I didn't see Brazil failing to win neither. Not like Brazil came out with some horrible third string level players neither, they had alisson, militao, silva, fred etc etc all the good players that they have and they still managed to fail to win. That bet probably was lost for many people, I feel like many people probably wagered on Brazil yesterday and they lost. It happens, it's football, sometimes you end up losing games and you just have to get up and continue like nothing happened.
There is really nothing that could be expected in football when the results are like this, but we could martingale out of it, next Brazil game will probably be a win.
