Everyone asks me if I know about it and I do not really know it. This year was very important in all respects: mentally, I managed to go through very complicated situations, in addition to managing new ones.
After great results, you feel the pressure, you ask yourself more questions and I had a bad sleep. I improved, my level went up. I can really compete with everyone.
It's hard against Novak Djokovic. There are many things that bother me. He's coming back very well, playing very well on the backhand, so it will be a very difficult game on the technical side. But there will be a very beautiful emotion.
We trained together in Cincinnati, it's a nice person. This year, I faced Roger Federer, Rafael Nadal and Andy Murray, he was the only one I did not face.
Berrettini also returned to his loss to Federer in the fourth round of Wimbledon: "At the net, I should have asked him how much does a tennis lesson cost him.
"I have great mental strength," continued Berrettini, "but also major technical weapons, although I do not have incredible physical skill. I have fast arms and I'm in shape because I played a lot of tough five-set matches. "
