On Tuesday afternoon Serena Williams will begin the defense of her French Open crown when she meets Magdalena Rybarikova on Philippe Chatrier.

By her own high standards, Williams’ made a slow start to 2016. But judging by her performance in Rome, where she lifted the 70th title of her career, she appears to be rounding into form at just the right time.

Ahead of her return to the French capital, CNN Open Court sat down Williams to discuss her love of clay, coaching set-up and the quest for Grand Slam title number 22.
