Emma Raducanu's Wimbledon campaign gets underway on Monday against a familiar foe - 17-year-old wildcard Mimi Xu. Raducanu knows the Welsh-born teenager well and even speaks with Xu's mother in Mandarin. But they will become rivals when they meet on Court 1 for day one of the Championships.
Xu is making her Grand Slam debut and hoping to follow in Raducanu's footsteps, four years after the British No. 1 got a wildcard into the main draw when she was just 18 and stormed into the second week.
