'Manic Monday' awaits at Wimbledon - arguably the best day on the tennis calendar. We've picked out just a few of the potential highlights.
Roger Federer v Grigor Dimitrov
Like whistling Mozart at a Metallica concert. That was what the late American author David Foster Wallace once wrote of Federer's tennis in this age of baseline power, though the Swiss' results this season have shown how classical can drown out heavy metal. Dimitrov's tennis is also classy, often inviting comparisons with Federer's game.
To keep that music theme going, it's unlikely that either of these two will whistle or even break out into song on Centre Court, but this is a meeting between members of a tennis boyband that have some have been calling 'The Backhand Boys'. Earlier this year, Federer released a video of himself, Dimitrov and Tommy Haas doing a version of 'Hard to Say I'm Sorry', a 1980s rock song by American group Chicago. Federer, who has ambitions of winning a record eighth Wimbledon title, and a 19th Grand Slam, is yet to drop a set all Championships, and Dimitrov hasn't either. Here's something else to ponder: Federer has won all five previous meetings with Dimitrov.
Angelique Kerber v Garbine Muguruza
They probably won't want to form a club, but a quarter of the 16 women remaining in the ladies' singles have been Serena'd in a Wimbledon final: Venus Williams, Agnieszka Radwanska, Kerber and Muguruza. And two of those past runners-up to Serena Williams will play in the fourth round, in a meeting between 2015 finalist Muguruza and Kerber, who featured in last summer's final.
Both have experienced Grand Slam success away from these lawns - Kerber was last season's Australian and US Open champion, and Muguruza took her first major at Roland Garros last year. But, with Williams seven months pregnant, this could be the summer when one of these two goes all the way through the draw. After all, this time there's no Serena to stop them.
It was 20 years ago this summer that Williams played The Championships for the first time and, just for emphasis, the Californian finds herself playing another teenager who has only lived through 19 of those Wimbledons. Williams' third-round opponent, Japan's Naomi Osaka, hadn't been born when Williams first took to these courts in June 1997, and neither had her fourth-round adversary, Konjuh, who came into this world in December 1997. The unimaginable happened at Roland Garros last month with Latvia's Jelena Ostapenko, who turned 20 during the tournament, taking her first major. And Boris Becker, who knows a bit about winning Wimbledon at an early age, is among those whispering that 19-year-old Konjuh has the game to excel on these courts.
Williams, who has won five Wimbledon titles, is the only former champion left. If she loses to Konjuh, a new name will be added to the honours board on Saturday.
Victoria Azarenka v Simona Halep
For any new mother, returning to work after maternity leave is not without its stresses. And that's just for an office job. When you're an elite tennis player, those pressures are only magnified by the physical demands and also by your every move being played out in public.
Azarenka, who gave birth to her son Leo just seven months ago, and who is playing her first Grand Slam as a mum, has performed to a high level in reaching the second week. If the Belarusian could defeat the Romanian, and then go all the way through the draw, it would be one of the most astonishing tales in Wimbledon's history.
No-one's claiming that the Grand Duchy of Luxembourg is among the tennis superpowers but in Muller it has a player capable of causing all sorts of difficulties for Nadal on this surface. This match brings back memories of the summer of 2005 when Muller defeated Nadal in the second round (that was very soon after the Mallorcan had won his first Grand Slam at Roland Garros). Nadal, though, can take encouragement from the other time they played at Wimbledon, as he won their third-round encounter at the 2011 Championships.
Martina Hingis and Sania Mirza
One of the highlights of Hingis and Mirza's doubles partnership was winning the 2015 Wimbledon title. But, such is the way in tennis, they now find themselves on opposite sides of the net at the All England Club in a third-round match. While Hingis is playing with Taipei's Yung-Jan Chan, Mirza's partner is Belgium's Kirsten Flipkens.
