Fifa have unveiled a new ball which will be used during the semi-finals and the final of the Qatar World Cup.
The ball is called Al Hilm, meaning The Dream, and will be replacing the ball used throughout the World Cup so far, Al Rihla - or The Journey.
Al Hilm will make it's debut during the semi-finals, leaving the teams playing just a few days to get used to the change of equipment.
Fifa said this technology has been 'invaluable in helping match officials making faster and more accurate decisions during this World Cup.'
The technology has allowed for offside decisions to be made more quickly as officials can see the exact moment the ball has been played forward.
The ball also helped to determine whether Cristiano Ronaldo actually got a touch on Bruno Fernandes' cross in Portugal's win over Uruguay.
The sensor inside the ball was used to say that Ronaldo didn't get the final touch - despite his elaborate celebrations.
Fifa say that the design of the ball has been inspired by the host nation and the World Cup trophy itself.
Fifa said the ball is made up of 'the sparkling deserts of the region that surround the city of Doha, the colour of the FIFA World Cup trophy, and the pattern of the Qatar flag.'
Nick Craggs, Adidas football's general manager added: 'Al Hilm represents a beacon of light on the power of sport and football to bring the world together'
The ball will first be used in Lionel Messi and Argentina's semi-final clash against Croatia.
