Milad Mohammadi pulled out a somersault, and then pulled out completely
Was this Iran player's throw-in the worst ever in a World Cup?
The throw-in is a simple technique as far as football goes - you don't have to be a professional to be able to take one.
A handful of players struggle with their hand-eye coordination, though, while others, such as Iran's Milad Mohammadi, are prepared to take the concept further by adding some gymnastics to the routine.
It would have been an impressive moment during last night's Group B match against Spain had Iran not been losing 1-0 and it being deep into injury time when Mohammadi decided it was time to show off his moves.
He collected the ball, kissed it, looked to the sky and then pressed it against his head before setting off on his head-over-heels attempt.
But then just as he was about to hurl the ball towards his waiting teammates, he appeared to be lacking momentum and pressed the abort button, leaving millions wondering what it was he was doing.
He then instead just threw it the traditional way to a teammate standing close by.
Social media was quick to point out how it should be done.
