Boris Becker worked with Novak Djokovic for three years, from 2014 to 2016, helping him to win six Grand Slam titles. The German enjoyed his experience with the Serb but there was one thing that annoyed him.
'Djokovic bouncing the ball drove me crazy when I was his coach, it drives me crazy now. It's a habit, it's his rhythm. He says, 'I just get into it, I don't think about it'. It's just what he does,' said Becker.
Becker also revealed an interesting thing concerning Alexander Zverev: 'Funnily enough, Zverev's mother can't watch any of her son's matches so she goes out to walk the dog and finds out the result with a phone call after the match.' Tim Henman said: 'It was Zverev's resilience and determination that finally wore Djokovic down today, which is very unusual.
Sascha definitely played much better than he did in the group stage. He deserved to win, he's still quite young but he's had an amazing career so far and I wish him all the best for his future. A German with a sense of humour who can talk and laugh at himself - a star has arrived.
The way he's carried himself, he understands the responsibility that comes with the title.' Zverev lost to Djokovic in the round robin match at the ATP World Tour Finals but defeated him in the final. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
