Same and all I've heard is his single handed backhand won't hold up which I completely disagree with. Most people who heavily follow tennis juniors knew Tsitsipas was a future slam champ a long time coming along with Shapa and Felix Auger Aliassime so it's not surprise that is coming to fruition now.
But he attacks better with his SH backhanded and I think it can hold up defensively better because he is a better mover then Nadal's opponents to date. I also think Nadal's tactic of standing 20m behind the baseline won't be as affective because Tsitsipas is better at the net and can shorten the points and play attacking tennis.
Plus he's the best mentally better player then all of the nextgen guys so I don't think the occasion will get to him.
