Mischa Zverev absolutely believes his brother Alexander has the room for improvement. Alexander, 24, is already one of the most successful player on the Tour from active players. Zverev doesn't have a Grand Slam title yet but he has won several Masters title, an ATP Finals title and an Olympic gold medal.
"Sascha has a lot of potential to grow as a player. Djokovic is 34 years old. His style of play is very mature," Mischa said, per We Love Tennis. "It's not as if Djokovic can still improve a lot, or that he can get much faster on the court.
Medvedev plays very, very good tennis. He does a lot of good things, in terms of playing style, tactics, technique. Of course, I might be wrong, but when I watch Medvedev's tennis he is also very mature."
'Alexander Zverev's baseline positioning resembles Roger Federer's'
Mischa mentioned the positioning from the baseline as one of the things Alexander could improve going forward.
"When I watch Sascha, there are still a lot of things he can improve: the preparation for the game, the tactics, the way of handling the big points. There is not one thing that is most urgent, but for example, we have to be careful with Sascha's position from the baseline," Mischa added.
"You need different positions against different players. It depends on how the opponent is playing flat or rotating. Medvedev and Djokovic do it so well. They always find the right distance for the opponent. "Sascha, I have a feeling he looks more like Roger Federer.
He likes to take his position on the court and play his game. But sometimes, if that doesn't work, he has to change positions faster." On Friday, Alexander Zverev saw off Hubert Hurkacz 6-2 6-4 to make the semifinal at the ATP Finals. Zverev will face world No. 1 Novak Djokovic in the semifinal at the ATP Finals.
