Watford shocked Jurgen Klopp’s Liverpool FC with a 3-0 win, but their first goal was the result of an absolutely mind-boggling mistake by stand-in goalkeeper Adam Bogdan.

Watford put in a spirited performance to upset Liverpool at Vicarage Road and their Nigerian goal scoring machine Odion Ighalo is showing no signs of letting up as he scored a brace in the game.

But Liverpool conceded the first goal after an awful mistake by Hungarian International Adam Bogdan, who was playing in place of regular goalkeeper Simon Mignolet. He messed up a simple save to offer a peach of an opportunity to Watford, which was taken up with glee by Nathan Ake.

Check out the video of the horrifying mistake below.
