New rule: From now on, all sporting events must begin with an official bringing the game ball to the referee via the magic of drone-style hoverboard vehicles. That can be the only conclusion after watching the absolutely insane demonstration recorded at the Portuguese Cup Final on Sunday, which started with a man riding on air, Green Goblin style, and landing delicately in front of a ref to deliver the game's soccer ball. It was what every sports event with a ball should have from this very moment on.
