Admittedly, it's not exactly crazy. But the male ponytail does look daft. Take a look at former Arsenal and England goalkeeper David Seaman. We're not sure anyone can pull off that look.

Say hello to Taribo West. We presume patriotism is the former Nigeria left back's excuse for this green hairdo. It matches the stripes on the Nigerian flag. The defender played for Derby County between 2000-01.

When the South African-born cricketer, Keven Pietersen, burst onto the international scene, everybody was talking about his destructive batting. It didn't take long for England fans to spot his blond streak. Ironically, the 34-year-old opened a hair salon this year. Let's hope he's not advising the stylists.

Former Brazilian striker, Ronaldo, was the man who until this summer held the record for the most number of World Cup goals. He sported a small patch at the front of his shaven head at the 2002 tournament.
The former American footballer, Antonio Garay, has gained a reputation for his colourful head designs. Looks to us like the ex-San Diego Chargers man has probably had every colour of the rainbow running through his hair at some point.

The Romanian football team decided to bleach their hair blond ahead of their final 1998 World Cup group match against Tunisia. The squad had already qualified for the last 16 after winning their first two matches. Following the change of hair colour, they drew 1-1 with Tunisia before crashing out of the tournament following defeat to Croatia.
