The last time Nadal won a hard court slam (2019 US Open) Monfils and Berrettini faced other in the QF and the winner of that match faced Nadal in the SF.
Medvedev was in the other side of the draw too.
Also, both Federer and Djokovic were out before the semifinals.
Meanwhile, fast forward to the 2022 Australian Open, guess what the potential draw looks like once again…eerily similar
I didn't see this post before, but I did notice this morning, looking at the H2Hs of matches after last night's results, the Berrettini d. Monfils (5 sets, btw,) QF USO 2019, so I did think, oh, that must have been the round before Rafa played Matteo, but I didn't think about other coincidences, such as Roger and Novak not being in the tournament anymore, at that point. Since
@Ellentonboy cautions us, rightly, not to look ahead, I won't, but there could be more coincidences with that tournament. I will hope so, and leave it there.
