Andrey Rublev vs Matteo Arnaldi

Andrey Rublev would be the clear favorite in this matchup. His power, aggressive baseline game, and experience playing at the highest level should give him the edge over Arnaldi.

Matteo Arnaldi could still make it competitive, especially if he manages to stay consistent and challenge Rublev's aggression with his defense. However, it's difficult to see Rublev losing in a match of this caliber unless he’s off form or facing a very exceptional day from Arnaldi.
