Who remembers those primary school days when a game of 'Headers and Volleys' was the greatest thing, ever?
It was an absolute classic, until that one kid smashed it on the roof and the ball was never to be seen again.
'Headers and Volleys' required plenty of patience and ability, but you had to put the hours in to really perfect the craft.
Just ask five of the Serbian national team, who put their practice on the training ground into action on Saturday afternoon during a friendly against Bolivia,
In the 42nd minute, a free-kick was whipped into the Bolivia penalty area.
It seemed like a wasted set piece, but somehow Mladen Krstajić's side produced one of the most incredible goals we've seen in some time.
Five volleyed passes later, former Chelsea defender Branislav Ivanovic smashed in from close range.
Serbia currently lead 5-1 in the friendly ahead of the World Cup next week, but this goal has deservedly grabbed all the headlines.
We're still not sure how this went in and neither do Twitter, who were in a state of shock when Ivanovic made it 4-0.
WHAT A GOAL!
