It is bad enough to make a jaw-dropping mistake at any time when you are a professional goalkeeper, but when a place in a competitive final is at stake you just want the ground to swallow you whole.
Nancy No. 1 Guy N'Dy Assembe will certainly be reluctant to show his face for a while after misjudging a bouncing ball during the side's Coupe de la Ligue semi-final against Monaco on Wednesday.
After the shot-stopper saw the ball wriggle through his gloves, Radamel Falcao was on hand to fire a header into the empty net and open the scoring.
To make things even worse for Assembe his blooper proved the difference between the two sides, as Monaco held on to win 1-0 and book their place in the showpiece.
The 'keeper may not want to see this again - but you can enjoy it right here!
