As Serena Williams enters the semi-finals at Wimbledon, her pop-culture influence is gathering pace and the seven-time champion wants to inspire in as many areas as possible for the good of her sport.

Serena Williams feels that the world needs a 'good story' and with every stroke she plays at Wimbledon, the seven-time champion is fast becoming the centre of attention in many areas beyond Centre Court.

The 36-year-old American showed on Tuesday that her warrior spirit can bring her out of the toughest situations; and it will take a ruthless competitor to stop her.

That was proved when she battled back from a set down to claim a 3-6, 6-3, 6-4 triumph over Italian Camila Giorgi for her first Wimbledon semi-final berth since lifting the title in 2016. 

Her progress in returning to tennis after becoming a mother in September last year has inspired many and Williams believes she has surpassed her own expectations.

"I think everything right now is a little bit of a surprise," said Williams, who has 23 grand slam titles to her name.

"To be here, to be in the semifinals. I mean, I always say I plan on it, I would like to be there, have these goals. But when it actually happens, it still is, like, 'Wow, this is really happening?'"

Williams plays German Julia Goerges next in their final four clash on Thursday and it hasn't been that long since their last meeting.

They met at the French Open in the third round of Williams' grand slam return at Roland Garros, and she insists it won't have any impact on their next match.

"That was four or five weeks ago," said Williams.

"That doesn't matter. This is a whole new match, it's a new surface, it's everything. We're starting from zero."

Also in attendance during a Williams main stage attraction are high profile fans. Former heavyweight boxer Mike Tyson was present in Paris and recording artist Drake flew in from the US to watch her latest win at Wimbledon.

Williams says it flatters her that she touches so many worlds outside of the tennis court and adds that it feels like she helps her sport evolve.

"It's so cool, especially artists like that, like Mike and Drake who are so successful, to come out," she said when asked about her celebrity circles after her victory against Giorgi.

"It feels like tennis is becoming part of pop culture. That's what I love about it. Just helping create that popularity, getting more young girls to play and be a part of such an exciting game.

"I never assumed or knew I would be in this position. It's, like, when I first started out, I was playing tennis. It just became greater than me. Sometimes it takes a while to realize that.

"I've always embraced being a role model. I think for me I just fell into that perfectly. Now that I'm a mom, I just want to even be more of that role model for my daughter.  Right now there's so much bad news in the world. We just need a good story."

And her peers on the Wimbledon courts and terraces have been equally impressed.

Twenty-year-old Latvian Jelena Ostapenko, who faces Angelique Kerber in the other semi-final, has made a few notes on Williams and feels that they would match up well.

"Her game style is probably similar to mine," said Ostapenko, who won the French Open in 2017.

"I always enjoyed watching her play and always learned some good things watching her."

Ostapenko has never played the former world number one but Kerber has and the last two meetings were in grand slam finals. 

Kerber, who is also a former world number one, beat Williams in the 2016 Australian Open final but lost in the Wimbledon showpiece in the same year.

The 30-year-old German feels that her biggest rival is on her way to great achievements.

"I think it's great what she has done so far," said Kerber.

"I think she's the best player. She's a champion. I have a lot of respect of her as a person, but also as a tennis player. I think she is coming back, for sure."
