Kinsey Wolanski - American pitch invader who disrupted Champions League final in revealing swimsuit - performs incredible acrobatic throw-in but can't decide if move is illegal

Kinsey Wolanski shared her somersault throw on social media and asked her followers to judge whether the move was legal or not. Fans seemed wowed by the cropped version of the Colombia 2018 World Cup shirt Wolanksi was sporting but replies from experts on the intricacies of the throw-in law appeared to be thin on the ground.

"Constant debate on this throw in…… illegal or legal?" Wolanski asked followers alongside footage of her performing the somersault throw.

Wolanksi caused an international stir when she invaded the pitch at the Metropolitano Stadium in Madrid during the 2019 Champions League final between Liverpool and Tottenham dressed only in a black bikini. The stunt seems to have done some good as she has amassed 3.7 million Instagram followers since.

The somersault throw-in has occasionally featured in high-level football but has never become a staple feature of the game. Newcastle United's Steve Watson was a famous early adopter of the technique, audaciously performing the routine as a 16-year-old before being advised by coaching staff to stick to the more conventional delivery.

Iran's Milad Mohammadi made an attempt to bring the flip-throw to the 2018 World Cup before being told not to bother by an unimpressed referee.
