In an interview to Tennis365, the former world No. 2 Tommy Haas praised his compatriot Alexander Zverev. The 21-year-old Hamburg native won his biggest title so far at the ATP Finals in London last month and eyes more success in 2019.
Haas said: 'Zverev has shown us already in the past what he is capable of with his Masters 1000 wins. He is growing in maturity and is a great competitor, but we should remember he is only 21. He has an amazing team around him, a family that has great tennis roots and an older brother in Mischa who will help him to understand what is needed to succeed on the Tour.
His performances at the World Tour finals were very impressive. To beat Federer and Djokovic back-to-back is not an easy task in such a big event, but he played so well and took the game away from these great champions. When he is moving well, hitting the baseline shots with such aggression and when that powerful first serve is going in consistently, he is a tough guy to stop.' On Andy Murray, Haas concluded: 'I had hip surgery and it can take a long time to feel good on the court after that,” he stated.
“Andy came back this summer and tested it out a little, but he will be hoping to come back properly in 2019. You need a year to get over that kind of surgery and I would never count him out. Andy Murray is a fighter and a competitor and he will not come back to the tour unless he feels he can compete.
Andy is still only 31, so he has plenty of gas left in the tank if he can overcome his physical issues, but the movement is so important for him. If he can come back and remove all the aches and pains you get from hip surgery, he will have a great chance.' ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
