World number one Jannik Sinner and defending women's champion Barbora Krejcikova play their third-round matches on Saturday - all you need to know.

Novak Djokovic returns to action at Wimbledon today as he faces his countryman Miomir Kecmanovic for a spot in the fourth round. Dan Evans gave the Serb few headaches last time out. Djokovic cruised to victory in straight sets to dump the Briton out of his home major and will hope to exact the same misery on the unseeded Kecmanovic.

Rising tennis star Jannik Sinner has acknowledged the influence of Novak Djokovic on his playing style, echoing John McEnroe's observations. After cruising into the third round of Wimbledon with a commanding victory over Aleksandar Vukic, Sinner drew comparisons to the 24-time Grand Slam champion Djokovic.
