Venus Williams has won 7 majors and 49 titles in her career, but one of her most remarkable achievement was reaching the Wimbledon final at 37 years of age after she was diagnosed with the Sjögrens Syndrome back in 2011. Venus frequently had to retire from tournaments in the past due to injury, illness, and fatigue associated with her disease, but the American has always found her way back.

Why Serena is proud of Venus.

After Venus reached on Thursday her 9th Wimbledon final, the Serena commented 

“I’m proud of her; everyone is proud of her. She’s such an amazing person, and she’s so nice, and she’s been through a lot obviously, but we are always rooting for her.

She’s been through her illness, and she keeps fighting through it, and it would just mean so much, not just for her but for people who suffer what she suffers just to realize that this isn’t, this doesn’t have to be it. You can go through what she goes through and still come out on top.

I have to believe that {she can beat Muguruza in the final], and I know she has to believe that. We work so many years for these moments that she has right now, and I’m really happy for her.” 

Serena has defeated Venus 3 times in the Wimbledon final (2002, 2003, 2009) while Venus beat her sister in the 2008 final.
