Alexander Zverev, failure to overtake Jannik Sinner is the'least of the problems

Alexander Zverev vented after his defeat to Matteo Berrettini in Monte Carlo: “I am not satisfied at all, I am winning almost no matches. So far, this is my worst period since I got injured”.
“I played the first set very well, but once I lost my serve in the second set I started playing ten times worse. My ball is very slow, I don’t run it at all. I stopped hitting the ball and for the last few months it’s been the same story. Nothing changes, it’s always the same story. Once again I was the one who lost the game. I think my current level is unacceptable.”
“I have no idea what is happening to me right now. I’ve been trying to figure it out for several months, but I don’t even know what to say anymore. I don’t know what to say. Theonly thing I know is that I am losing matches, that”.
“If I had won two or three matches like this, fighting so hard, there wouldn’t be so many questions, but I lost in three sets in Buenos Aires, in three sets in Rio, in three sets in Indian Wells, in three sets in Miami and in three sets here.”
