Not such a big amount compared to bets shared here, but if it hits, it will be really big for me
Did anyone imagine Arsenal would be competing for a "small" double this season?
Ouch! If I knew it was going to be a loss maybe keep it to yourself next time.
But don't worry about it, I had the exact same thing happen to me with my bet believing in a Paris St.Germain win:
It was a small stake amount so nothing lost and with your freebet for the one above in your post, you didn't lose anything either as it being only a factious stake with no funds deposited to use on your wager.
I put in a similar bet but in an acca @793.88x odds for the next Arsenal match in the EPL during the weekend.
So if that does not hit. Again: Not a thing lost.
