The era of the 'Big Three' may be coming to an end - but the threat has not disappeared.
Players born in the 1990s were restricted to just two Grand Slam singles titles between them as Roger Federer, Rafael Nadal and Novak Djokovic diced up the major prizes for more than two decades.
Two players born after 2000 have captured seven major titles between them.
That is the current top two of Jannik Sinner and Carlos Alcaraz, who are on a collision course in Paris.
But Novak Djokovic still looms large.
The 38-year-old faces Sinner - who is 15 years younger than him - in Friday's first French Open semi-final, having become the oldest man to reach the last four since 1968.
