Novak Djokovic reached the Wimbledon quarter-finals for the 16th time but it proved a hard day's work at his Centre Court office as he ground past Australian Alex De Minaur on Monday.The 38-year-old started abysmally and lost the opening set in 31 minutes but eventually gained control of a cagey battle to win 1-6 6-4 6-4 6-4 to keep alive his quest for an unprecedented 25th Grand Slam title.

Novak Djokovic has overcame an uncharacteristically unsteady start to avoid what would have been his earliest exit at Wimbledon since 2016.

The win marked the 16th time Djokovic has moved into the quarterfinals at Wimbledon. The event has been his second-best Grand Slam over his career. Djokovic has seven wins at Wimbledon, and has played in the final at the event in each of the last six Wimbledons.
