Serena Williams’ former coach, Rennae Stubbs, said she would welcome the opportunity to work with Emma Raducanu as the Brit’s concerning form continues. Raducanu is currently enduring the worst losing run of her career after another first-round exit at the Qatar Open last Sunday.

Emma Raducanu’s miserable coachless run continued as she lost in straight sets to Ekaterina Alexandrova, the same Russian she had defeated in the opening round of last month’s Australian Open.

Emma Raducanu needs a stronger mentality to find success on the court, according to Serena Williams' former coach Rick Macci.
