Jankovic at her dramatic best will lead, throw the lead away, spot you a massive lead in the third set, decide to come back with some blazing retrieving and backhands, almost comeback, and then hand you the win, possibly with back to back double faults or netted forehands. You have no agency in this match. You might start to wonder if you have free will. Perhaps solipsism is true after all - is it Jankovic's world and you're simply allowed to live exist in it? It's basically existential waterboarding.
Serena: "We have great personalities like Jelena (Jankovic) on the tour." Jelena: "If I had to pick someone after me, I'd pick Serena."

As for me I would be already happy to see Alexandra somehow finding her way back into the Top 100 again. It really doesn't look as if her body allows her to be capable of more than that. However, I wouldn't rule her out in the AO qualifying event if the draw opens up for her.
