Keep dreaming. This is his second singles match after 7 months out. In that context he looks fine. DGT has been playing pretty well. Nadal's far from his best but I expected a lot worse to be honest. Takes time to get confidence and that match readiness. He has plenty of tournaments to get that before Roland Garros.
So first you say "keep dreaming" and then you agree with me?
He is beatable, deal with it.

We should be appreciative of Federer though, because we will never see anything like him again. The fact he can still compete for slams ever after the erosion of his physical skills is really a greater testament to the natural talent he has than the period of time when he was dominating the tour.
