Venus, The 'Perfect Sister' Inspiring Serena's History Bid

Serena Williams hailed "perfect sister" Venus as the inspiration for her march towards tennis history after the five-time champion won their Wimbledon showdown on Monday.

Serena was relieved to have beaten the only player she regards as her equal, in the process ensuring she remains on course to become the first woman since Steffi Graf in 1988 to win all four Grand Slams in the same year.

But the 33-year-old, bidding to win her fourth successive major title and 21st in all, was quick to hail Venus 35, for providing a life-time of inspiration. (Sharapova Endures Tough Test)

"I always say I wouldn't be the player I am today if it wasn't for Venus," Serena said.

"Just having an opportunity to watch her win matches, watch her go to the top, and me wanting to be there because she was there. (Wozniacki Ousted by Garbine Muguruza)

"Her practising next to me on the court. That inspiration, her inspiring me.

"Venus does nothing wrong. She's like the perfect sister."

Serena conceded she would much rather not have had to secure a 15th career win over Venus, but she was happy the unwanted match-up gave her a chance to reflect on their epic achievements at Wimbledon, where both siblings have won five titles.

"Sometimes you have to play people that you don't want to play. That happens," she said.

"But I just really was enjoying the moment out there. It was such a great vibe, such a great situation to be in, when we were both so young and dreaming of coming to Wimbledon.

"Not only did we fulfil our dreams, we both won it five times. That's pretty amazing."

- Sisterly words -

Taking on Venus hasn't got any easier for Serena despite her winning record in their rivalry.

"In the past I had to really pretend like, 'No, I'm not playing Venus'," said Serena who tackles Victoria Azarenka on Tuesday for a place in the semi-finals.

"But now I was thinking, I'm playing a tough opponent. She's been playing so well. Oh, my God, how am I going to be able to overcome this?"

After exchanging "sisterly words" at the net, Serena wants to put the reunion behind her and power through the rest of the tournament.

"I look forward to tomorrow. I feel like my tournament has finally begun," she said.

"This is where I feel really comfortable in a Grand Slam."

Venus agreed with Serena that there was a familiar sense of unease when the sisters realised they would be facing each other.

"Playing before the later rounds is definitely not ideal, in particular because I'm her sister," she said.

"It's anti-climactic if this isn't a semi-final or a final.

"Especially when she's going for something this historic, which is achievable for her."

If Serena does complete the calendar Grand Slam, she would draw level with Graf on 22 major titles -- second only to Margaret Court's 24.

And Venus has no doubts her sister will be regarded as the best ever by the time she is finished.

"The level she's playing at is unprecedented. I can say that with confidence. So make what you will of it," Venus said.

"She's not done yet. Then when it's a wrap, it will be easier to make labels and not offend anybody."
