When the French Open draw was made a fortnight ago, it was the potential women's match that everyone wanted to see.
Iga Swiatek - the reigning champion known as the 'Queen of Clay' - against world number one Aryna Sabalenka in the semi-finals.
The pair have dominated the WTA Tour over the past three years, leading to an era-defining rivalry that resumes when they meet in the last four at Roland Garros on Thursday.
"It is the blockbuster of the entire tournament on the women's side," said former world number nine Andrea Petkovic, who will be analysing the match for BBC Radio 5 Live.
