Petchey advises Raducanu to focus on closing the gap between herself and the best players, suggesting she may need a new coach if he isn't the best fit.
Petchey notes that changes in the game, such as heavier balls, make it harder for Raducanu, who isn't a big hitter, to compete on certain surfaces.
Petchey defends Raducanu's work ethic, dismissing claims that she doesn't work hard and emphasising her commitment to training.
