Novak Djokovic described his Wimbledon fourth round match against wild card Tim van Rijthoven a 'very good fight' as he extended his Centre Court winning streak.
Djokovic was tested by the Dutchman, who was able to up his level in the second set and make the defending champion work for it.
However, the Serbian was, as usual, up for the challenge as he secured a 6-2, 4-6, 6-1, 6-2 win and a quarterfinal date with Jannik Sinner on Tuesday.
Van Rijthoven came to Wimbledon riding his own winning streak that included beating world number one Daniil Medvedev in the final of 's-Hertogenbosch, but Djokovic said he went into the match knowing what to expect.
"I knew coming into the match that it was always going to be a tough, challenging matchup against Tim, who I've never faced before," Djokovic said.
"I watched him play. He's got a really good game for grass, which he proved today. Was a very good fight, especially in the first two sets.
"But overall I think I've played very well, very solid from back of the court. I got into his service rhythm, started reading his serve better in the third and fourth sets.
"I just really am pleased with the way I closed out the match. I lost the rhythm on my serve a little bit towards the end of the match, but overall just a good fight and really challenging match for me on grass."
Novak Djokovic has now won 25 matches in a row on Centre Court - a run of results that dates back nine years.
The last player to beat Djokovic there was was Andy Murray, who beat him in the final of the 2013 tournament.
