The Class of 1992 is better than ever according to John Higgins, who will be in the World Championship quarter-finals.
On Tuesday, O'Sullivan and Williams face off, as well as the other game between Higgins and Jack Lisowski.
The trio, who have 13 world titles between them, have not reached the last eight together since 2011.
The other last-eight match is between Judd Trump and Stuart Bingham.
Mark has been playing very well and he is playing against a very tough player inRonnie. He is the best player he has ever been, because he might have thrown the towel in beforehand.
It has been 30 years and the three of us are better players than we have ever been.
The other two guys might have differing opinions. I looked at them from the outside, playing against them and watching them.
The Englishman was thrashed 13-1 by the four-time world champion in their only previous meeting at the Crucible.
He says that result won't affect the outcome this time.
Jack Lisowski has a chance to write his own chapter in this tournament.
He will feel like he can beat anyone if he beats Neil Robertson. It makes him dangerous.
Six-time champion O'Sullivan registered a record-breaking 71st victory at the Crucible in his 13-4 second-round win over Mark Allen.
He said that he was able to stay at the top of his game because he followed the same approach as Bruce Lee.
It takes quite a few years of practice and dedication to be the best version of yourself.
Bruce Lee trained for many hours, not just mentally but physically. We are experts in different fields but I try to approach my sport the same way. I struggle with it, to be honest.
He will face a rejuvenated Maguire in the next round, a two-time Crucible semi-finalist who beat UK champion Zhao Xintong in the last 16 with a borrowed cue.
Maguire should have been world champion.
He has a world champion game and he is still playing very well. He made six centuries in the final of the Tour Championship a long time ago.
Stephen Hendry is a seven-time world champion.
The second week is when you want to peak. When you get to the one-table set-up, you're only halfway there because you play so many frames in the semis and final.
I think he is the man to beat. He is playing well. He looks composed and focused.
The quarter-finals schedule is best of 25 frames.
