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.
