Three of the top four seeds are through to the semi-finals of Wimbledon and it is hard to predict who will be crowned champion on Sunday.
Richard Gasquet ended another outstanding day of action at Wimbledon with a stunning victory over Stan Wawrinka, but it is difficult to envisage one of the top three seeds failing to secure another grand slam title on Sunday.
Frenchman Gasquet won a marathon quarter-final against the French Open champion 6-4 4-6 3-6 6-4 11-9 on No.1 Court to reach the last four at the All England Club for a second time.
The result maintained a remarkable run at Wimbledon which stretches back 20 years, during which time it has never transpired that the top four seeds have made it through to the semi-finals of the men's draw.
Gasquet, 29, will have a day to put his feet up on Thursday as he prepares to take on world number one and defending champion Djokovic.
The outstanding Djokovic has won 12 of his 13 matches against Gasquet and will be heavily fancied to improve on that record.
Defending champion Djokovic oozed class as he saw off Marin Cilic in straight sets to stay on course for a third Wimbledon title and a ninth grand slam crown.
The sensational Serb was taken to five sets by Kevin Anderson in a fourth-round encounter that spanned two days and saw Djokovic fight back from two sets down.
He was intent on not being put through another test of endurance against Cilic, overcoming the US Open champion in an emphatic display.
If Djokovic does advance to another Wimbledon showpiece, he will be keen to avoid more heartbreak after Wawrinka consigned him to defeat in the French Open final last month.
But whoever comes through the semi-final between top seed Djokovic and Gasquet will surely have to be at their best to win the title as Roger Federer and Andy Murray have been in such impressive form in London.
Seven-time Wimbledon champion Federer was imperious once again as he saw off Gilles Simon in straight sets on No.1 Court.
The Swiss master, who is eyeing an 18th slam triumph, will now face Murray in what promises to be a classic between two players at the top of their game.
Murray also needed just three sets to beat surprise package Vasek Pospisil and looks more than capable of winning his home grand slam for a second time.
Regardless of which two players progress on Friday, the final looks set to be a thriller as the leading men in world tennis continue to raise the bar.
