Is the World Cup ball rigged?

The World Cup's new ball is the most technologically advanced ever, Fifa tells us. It has a 500Hz motion sensor chip, which lets VAR and analysts figure out precise positioning, speed and even the spin on the ball, for some weird reason. But former England goalkeeper Joe Hart says the Trionda ball is making life harder for goalkeepers trying to save shots. He said: 'As soon as [players] are not using the curling technique, as soon as that ball is not spinning, the goalkeepers are struggling.'
