It doesn't matter what the occasion or circumstances are, whenever Roger Federer and Rafael Nadal meet, tennis fans around the world gather to see what happens.
The most recent clash on Wednesday evening was the 36th time the two modern greats have faced off and yet there is little sign of the public losing interest in one of the greatest rivalries the sport has ever seen.
For the third match in a row between the pair, it was Federer who emerged the victor, winning 6-2 6-3 and progressing through to the quarter-finals at Indian Wells.
Nadal struggled to handle the Swiss star's aggression and fell to the same fate he suffered in the epic Australian Open final two months ago.
In previous encounters, Nadal has often tried to target Federer's one-handed backhand but his old adversary was equally potent on both sides.
Part of the charm that has made their contests so engrossing over the years is the amount of respect they have for each other.
On the court, the duo are fiercely competitive - hence why they have had so much success - but after putting down the racquets they become great friends.
In fact, a video that has emerged capturing the scenes before Wednesday's match arguably sums up their relationship.
Bizarrely, the pair both made they way from the changing rooms to the court via a golf buggy.
But as you can see below, even though Federer and Nadal have to share their mode of transportation, neither exchange even the slightest glance or word of conversation.
It looks incredibly awkward.
Both men were clearly in the pre-match zone and tried to not let the close proximity of their opponent distract them.
But it proved to be Federer who rose highest to the occasion and thereby sealed his place in the last-eight.
With Andy Murray already out and Novak Djokovic and Nadal exiting last night, Federer will back himself to go all the way at Indian Wells.
The next challenger who stands in his way is Djokovic's conqueror Nick Kyrgios.
The Australian will certainly feel buoyant after becoming the first man to beat Djokovic in the Californian desert since 2013.
