I had two free bets and won one of them in the same way like you. To be frank, I was expecting Brentford to win the match as the odds were high for them. I was a bit surprised when they scored a goal in the first half. But the ending was completely unexpected. Brentford had a great opportunity to take the lead during the injury time, but their players had messed it up. Anyway, I'm satisfied with the small win.
