On Sunday, one Arsenal fan had a double reason to celebrate.

His beloved London club confidently won 5-0 in a Premier League match against Nottingham Forest.

Moreover, before the home game, he decided to test his luck in betting and made a difficult to understand bet.

The fan guessed that the Gunners would win the match 5-0 and that Gabriel Martinelli would score the first goal.

Due to these predictions, the Arsenal fan won 34 times more than he bet - 4250 British pounds.
