In an interview to Spox, the American tennis coach Nick Bollettieri commented on Alexander Zverev's mentality and character. The German is having a tough year and he only won one title in Geneva. "Zverev raised unbelievably fast", admitted Bollettieri.
"This is one of the reasons why he has some problems. And the major reason is that he is too emotional. Zverev should look at videos and see how he gets angry when he misses balls. In order to win a Grand Slam, he needs to grow mentally.
He has this big serve, he has the power on his shots, but he is not ready on his mind yet." Ivan Lendl is back to help him in Stuttgart. Can it help him? "I think he should help himself first of all. He needs to be able to face all that happens on court, become mentally hard and stay positive.
That will be the key to his future." On the women's game, Bollettieri concluded: "Anyone can win. If Serena is not healthy now and she cannot move the way she needs, everything is open for the women. It's almost impossible to predict something because so many players can win."
In a press conference in Stuttgart Zverev said: “I started practice yesterday. I didn’t hit for too long because of the rain, but I hit a little bit today already, I hit for two hours. I’m going to practise again later if the rain stops.
I’m going to do everything I can to prepare myself the best I can. I’m going to play doubles as well with my brother, so for me, I’m taking this tournament and the grass-court season very seriously. I want to do well."
