Friends and family of Craig Gordon, avert your eyes now.
The Celtic goalkeeper came up with a horrific howler during the Hoops' Europa League clash with Fenerbahce on Thursday night.
With Lazar Markovic bearing down on goal, Gordon took his eyes off the ball and allowed it to glide through his legs under almost no pressure.
Three sliding defenders couldn't stop the on-loan Liverpool man from finding the net and Celtic look on course to drop out of Europe with a disappointing three points to their name from 18 available.
The error was so bad that Markovic didn't really want to celebrate the goal and when that's the case, you know you've had a mare.
