EMMA RADUCANU AND GEMMA CHAN are reminiscing about their school days. Though the pair have never met in person, and there are 20 years between them, they have a lot in common. They both grew up in Bromley, south-east London, and went to the same school, Newstead Wood. ‘I think our house won Sports Day six years out of the seven I was there,’ says Raducanu. ‘I bet!’ replies Chan, smiling. Their conversation feels easy, like one between old friends rather than a first-time meeting over Zoom.
