Wimbledon champion Serena Williams believes her own “fear and doubt” are the biggest obstacles to completing the elusive calendar Grand Slam.
Williams claimed “I feel vulnerable every time I step out on court”, despite sealing a second ‘Serena Slam’ by hogging all four major titles at the same time.
The 33-year-old saw off Garbine Muguruza at the All England Club on Saturday for her 21st major triumph, and can complete her 2015 dominance of the big four tournaments by retaining her US Open title in September.
Williams revealed her soundtrack to success as Irene Cara’s 1980s classic ‘Flashdance... What A Feeling’ - the song she sings in her head to stay focused on court.
“You’d be surprised how I feel: I feel vulnerable every that time I step out on court,” said Williams, now the oldest women’s major winner in the open era.
“Every single time it’s overcoming those feelings.
“I’m always one of my biggest competitors: I can always stop myself.
“I just try to stay positive on the court, stay really focused and just as calm as I can.
“Physically I have to make sure I feel good: right now I feel really good so I’m interested to see how I’ll feel going into the hard court season.
“At any time fear and doubt can stop me too. So then I go back to singing - it’s crazy!”
