Nadal would much rather play Tsitsipas than Zverev for a place in the semis imo, and would much rather play Medvedev than Djokovic for a place in the final. Rafa is playing really well, he shouldn't be underestimated. He can now just see it as a knockout event from now on, and he got the two players he would rather face in his path IMO.I would not give anything to Nadal. The way Medvedev played vs Novak, he can easily beat Nadal as well.
Remember last year Medvedev was dominating Rafa completely before choking.
And then Nadal has to get through Titspas which is NOT a given.
Of course it will not be easy, this is the WTF, top guys here everywhere, but Rafa won't go down easy. He was barely beaten by 100 mph bombs by Thiem, it wasn't like he was outplayed completely. Novak went down easier here.
