The problem is that they haven't won anything recently. He lost and FO, he was eliminated 1/4 in Wimbledon... If he had a bit of ambition, he should have used it to win medals at the Olympics. And what does he do? He runs away. Joke. Alcaraz, in turn, recently won a double in the Slams, and yet he is motivated to play in Paris and fight for two gold medals. For me, Sinner will never have the mental of a great champion like Nadal, Djokovic etc. Their additional difficulties make stronger. In case of Sinner weaker and he gives up.
