So, naked Serena Williams shocks her tennis rivals in the locker room and dressed on the tennis court
Serena is just so gifted, it's unbelievable. I think her "genetics" will always make her look a bit chubby - unlike Venus - but she didn't look very match fit to me often times anyway, because she isn't/wasn't looking too much after her fitness and enjoying a more non-professional diet. However, in whatever shape she showed up, she was always such a force on the court. She didn't even need to be match fit to crush her opponents and that speaks for itself. Not to mention her mentality and self-confidence even when staring at defeat, which only few can match - Venus, Azarenka, Sharapova maybe.
If she was in top shape like Halep, Kerber, Dementieva she literally would be unbeatable and would be the GOAT forever. But every player has their weakness, which is good
