John McEnroe has raised a criticism of the tennis system, proposing a solution, regarding the doping issues that involved Iga Swiatek and Jannik Sinner last year.

Iga Swiatek, a self-described “control freak,” is taking new precautions — including holding on to extra samples of medicine she takes, in case they need to be tested at some point — after a doping case she describes as probably the worst time in her life.

Emma Raducanu might've been beaten but says she was grateful to be fully fit and playing at a high level again after overcoming a succession of injuries.
