Rabonas & fake births - Chelsea win World Sevens

With rolling substitutes, no offsides and 15-minute halves, the seven-a-side format is designed to bring out creativity.

Staff members and officials get involved in the fun too - Tottenham boss Martin Ho wore a fluffy blue cowboy hat, while London City Lionesses manager Eder Maestre celebrated with Nikita Parris using a special handshake.

One of the most elaborate walkouts involved Chelsea manager Sonia Bompastor as she was carried out by her team for the semi-finals and flipped to the ground.

"I enjoyed it. It came from the players. I'm someone who is usually quiet and I don't want to get too involved but that was a good opportunity," said Bompastor.

"We only practised it a little bit in the locker room. I made a joke that the players who didn't get enough minutes would have the opportunity to drop me!"

Bompastor borrowed a camera off a nearby photographer and pretended to film the players before their final, while Manchester United boss Marc Skinner came out dressed in a white dressing gown and sunglasses to a guard of honour.

Officials stole the show as they pretended to be wheelbarrows, led a rendition of 'Sweet Caroline' and performed a penalty shootout before kicking off matches.

Everton spent time before their 5-2 semi-final defeat by Manchester United to design a fake coffin which turned out to be a black suitcase with defender Hannah Blundell hidden inside during the walkout.

Toffees striker Katja Snoeijs also pretended to give birth as her team-mates (the midwives) delivered a football instead of a baby. It had pictures on of the injured players who could not compete.

Chelsea's players pretended to be tenpin bowling, defender Ellie Carpenter and midfielder Wieke Kaptein did the worm and Aston Villa teenager Rachel Maltby backflipped.

On the pitch, Chelsea striker Aggie Beever-Jones shone with a rabona assist for Erin Cuthbert and United's Melvine Malard celebrated by pretending to need CPR.
