A Manchester United fan had a rare and unexpected stroke of good luck after accidentally betting the side would be crushed 4 - 0 against MK Dons.
Twitter user Holly Griffiiths claimed she thought she had bet on Manchester United to win 4 - 0.
Instead, she bet on League One side MK Dons by mistake - at 500 to 1.
"Oh my god as if I won this on a free bet that I thought I was putting on united oh my god oh my god," she tweeted.
According to bookmakers Paddy Power, some 14 people placed similar bets for the Red Devils to lose by such a margin.
Manchester United suffered one of the most humiliating defeats in their history as they were defeated 4 - 0 by MK Dons during the League Cup clash.
The side have yet to win a match since the start of the new Premier League season.
United's new boss Louis Van Gaal - now without a win in three matches - watched on in misery as his team were knocked out of the Capital One Cup.
