Djokovic breaks Wimbledon record with win over Safiullin to reach quarter-finals

• Djokovic clinches 106th singles victory at Wimbledon

• 39-year-old continues quest for 25th grand slam title

In his quest to win a record-extending 25th grand slam title, Novak Djokovic cares only about results. How perfectly he plays holds less importance. On Sunday he was pushed hard by the Russian Roman Safiullin, and at times he cut a frustrated figure on Centre Court as his game didn’t flow the way it usually does. But for a record 106th time here, he came out on top, reaching the quarter-finals for the ninth time in a row and a 17th occasion in all. The 39-year-old has now made the quarter-finals of a major tournament 66 times.

Djokovic’s 7-6 (6), 6-3, 3-6, 6-3 victory against Safiullin required almost three and a half hours of effort on another warm afternoon in which he was rattled at times, mostly by the performance of the Russian, who played far more like his career-high ranking of 36 than his present mark of 132. Safiullin had two set points at 5-2 in the opening set only to be edged out in a tiebreak and was good enough to take the third set before Djokovic raised his game at the start of the fourth to avoid it going to a decider.
