Novak Djokovic faces Alexander Zverev in a blockbuster French Open quarter-final as the Serbian continues his bid for a record-extending 25th grand slam singles title.

For all of Novak Djokovic's titles (100 in all) and Grand Slam trophies (24) and weeks at No. 1 (428, more than anyone else in tennis history), for all of his talent and determination, the guy still can find himself worrying about what is going on with his game.

Three-times champion Novak Djokovic roared into the French Open quarter-finals by beating Briton Cameron Norrie 6-2 6-3 6-2 for his 100th match victory at Roland Garros on Monday to join Rafa Nadal in one of sport’s most exclusive fraternities.
