Serena Williams says she's still not sure she's made the right decision to launch her sensational Wimbledon comeback - but she's made it clear she's been studying the challenge her young Australian opponent Maya Joint presents.
The 44-year-old seven-times champion, admitting she never imagined she'd be back playing at the All England Club after nearly four years away from singles action, conceded she's going to be nervous on Tuesday and had to give herself a pep talk just to persuade herself to take up the offer of the wild card.
"I thought I should really take this opportunity. Who knows if I'll ever make it here again? This could be it," admitted the 23-time grand slam champ, who reckoned that playing at Wimbledon felt just like "riding a bike" again.
