AEK Athen's midfielder Giorgios Katidis has been banned for life from the Greece national team for performing a Nazi salute after scoring in his side's 2-1 victory over Veria on Saturday—despite claiming to not know what the gesture meant.
In recognition of Katidis' ill-advised gesture, here's ten more regrettable celebrations from world football...
In 1999, Robbie Fowler was no stranger to controversial goal celebrations, having been fined for supporting Liverpool dockers with an undershirt two years previously.
After finding the net in a match with Everton, the striker ran to the touchline and pretended to snort it, referencing (false) rumors that he was a drug user. His club fined him £60,000.
Katidis isn't the first player to celebrate by indicating fascist allegiance. While playing with Lazio, Paolo Di Canio gave the Nazi salute several times, receiving a ban and £7,000 fine on one occasion.
Sepp Blatter insisted a lifetime ban would have been more appropriate. In his defense, Di Canio simply said: "I am a fascist, not a racist."
While playing for Glasgow Rangers, Paul Gascoigne celebrated a goal in a January 1998 Old Firm derby by mimicking playing a flute. That's a loyalist symbol of Orange Order marchers, which enraged Celtic fans.
Gazza received death threats from the IRA and a £20,000 fine from Rangers.
Few people in the game can pull of front- and back-flip combos quite like Lomana LuaLua.
His days of somersaulting ten times in a row were cut short at Portsmouth, however, when he injured his ankle during a landing. After leaving the south coast, he soon picked up the habit again, though!
In a match with LA Galaxy in September 2008, Argentinean striker Fabian Espindola scored a glancing header and celebrated with his customary acrobatics. During the celebration, however, he injured his ankle and subsequently ruled himself out for eight weeks.
To make matters worse, the goal was ruled out for offside.
Plenty of footballers have paid tribute to their kids while celebrating: Luis Garcia would suck his thumb, while Francesco Totti once celebrated a goal against Lazio by putting the ball up his shirt and simulating childbirth!
One of the more annoying celebrations of this ilk was Carlos Tevez retrieving a pacifier from his sock to suck on. It looked as if Leo Messi was attempting the same trick after his son Thiago was born, but didn't get the chance.
After executing a superb goal for Milan in November 2008, the mighty Zlatan Ibrahimovic injured his elbow simply by throwing his arm up in celebration.
He soldiered on and played the rest of the game, but avoided being quite so enthusiastic with his fist pumping from then on.
While celebrating on the pitch after a victory in the 1993 League Cup Final, Arsenal captain Tony Adams attempted to put teammate Steve Morrow on his shoulders. Morrow slipped and ended up being stretchered off the pitch with an oxygen mask, having broken his arm.
Not technically a goal celebration, but fully deserving of a place in this regrettable countdown.
While at Chelsea, Nicolas Anelka went through a spate of celebrating with a "butterfly" hand gesture. It was terrible and absolutely no one else tried to imitate it.
WARNING: Graphic video
Never wear your wedding ring while playing football. If you do, never try to climb a perimeter fence after a goal celebration.
Portuguese midfielder Paolo Diogo did this in a Swiss league match in 2004 and ripped off the top of his finger when the ring got caught.
The finger was recovered, but surgeons were unable to reattach it. To make matters worse, Diogo was given a yellow card for time wasting!
