Who'd be a goalkeeper, eh?
Viktoria Plzen's Matus Kozacik must have gone to bed last night considering a career change after letting this goal in against CSKA Moscow.
But if this article was published before he went to bed, maybe he would have slept a little easier.
You're not the only 'keeper to be left red-faced, Matus...
Massimo Taibi v Southampton
Look up any list of Manchester United flops - or Premier League, for that matter - and Massimo Taibi's name will inevitably appear.
The Italian joined United in 1999, played four matches, and left less than a year later.
Matt Le Tissier's speculative long-range effort somehow managed to squirm under the hapless 'keeper's grasp - leaving both Taibi and his manager, Sir Alex Ferguson, red faced.

Shay Given v Coventry City
"He's behind you!" is what someone should have shouted to poor old Shay Given when he rolled the ball out in front of him.
The Coventry City fans, to be fair, did fantastically well to keep quiet as Dion Dublin crept up behind the Newcastle United goalkeeper.
Given didn't even have time to blink, as Dublin moved in quick as flash to roll the ball into the empty net.

Rene Higuita v Cameroon
Rene Higuita was a true maverick. Type his name into YouTube and watch him embark on several mazy runs. It's a remarkable sight.
But the Colombian's penchant for a crazy dribble cost him dearly when it mattered most: in the last 16 of the 1990 World Cup finals against Cameroon.
Higuita attempted to dribble himself out of trouble before the clinical Roger Milla dispossessed him and slotted the ball into the empty net.

Radu Mitu v Rapid Ghidighici
Radu Mitu cemented his status as a YouTube legend earlier this year when he threw the ball into his own net.
Imagine this: it's your debut for Moldovan side Milsami-Ursidos and you're playing against the mighty Rapid Ghidighici. You'd be keen to impress, right?
Well, sadly for Mitu, his eagerly-awaited debut was marred by this hilarious - sorry, terrible - gaffe.

Peter Enckelman v Birmingham City
Premier League legend Peter Enckelman is famous for this glorious boot upfield from a Olof Mellberg throw-in.
Oh no, wait. Premier League laughing-stock Peter Enckelman is in fact, infamous, for somehow allowing Mellberg's throw-in to roll under his foot and into the back of his own net.
Oh yeah, and he done it in a Second City derby against Villa's fierce rivals Birmingham City.
Not a good night at the office for big Pete, who must have been Matus Kozacik's idol growing up.
