Zverev refuses to reveal 2018 goals
World number four Alex Zverev says he has set a goal for 2018 but refused to go into any details.
The German enjoyed his best ever campaign in 2017 as he rose to a career-high world number three in the rankings and reached the fourth round of a Grand Slam for the first time at Wimbledon.
The 20-year-old won titles in Rome and Montreal and hopes to continue his development in 2018 but says his targets will stay with him for the time being.
"Last year was making London [for the ATP Tour Finals] - finishing inside the top eight was my goal," Zverev told AAP. "Some people thought I was crazy when I told them that at the beginning of the year. I was number 24 in the world.
"My team wasn't saying it was impossible but they were kind of laughing about it a little bit.
"This year I have a goal as well and I'm going to keep it to myself for now. It's not a ranking-related one."
