Serena followed in Venus' footsteps and began playing tennis after watching her as a kid, but ended up as the more accomplished player. Venus called Serena "the greatest ever" during a recent interview with Glamour UK."Serena has taught me so much and there’s so much you can learn just from being around greatness and that’s what she is - the greatest ever," Venus Williams said.The 42-year-old also said that she feeds off her sister's success and uses it as motivation."It’s more of a motivation and when I see her doing great, it’s my success. It’s also motivating for me and lets me know I also can do that, and that’s how you have to look at other people’s success," Venus Williams expressed.Serena Williams recently played her final professional match at the US Open, but has been giving slight hints about a comeback. Meanwhile, Venus Williams last played at the US Open as well and has not confirmed her future plans with regard to the 2023 season.
