Nikolay Davydenko recalled his 2009 ATP Finals triumph in London. The Russian said: "I lost in three sets to Djokovic. I beat Nadal and Soderling in two. Against Novak I won the first set, I lost the second and I felt tired, I could not understand anything.
I faced Federer who I had lost to ten times. I go out there and I think, 'What, for the 11th time?' But I played well, made my best effort and I was lucky to win, which helped me mentally. I beat Federer so I could make it.
Then I beat him in Doha too. I was very tired after the win over Federer in London and before the final against Juan Martin del Potro I remember I warmed up for five minutes, I hit three shots from the baseline, I hit two serves.
I was so tired I could not stand up. I needed to play faster because I could not deal with him for a long time." Meanwhile, Jan-Lennard Struff, who will play the ATP Cup in Australia with Alexander Zverev, spoke about how he started playing tennis: "I started playing with my parents, who were both tennis coaches.
I really enjoyed playing. When I was a small kid, I always loved to go out and I played soccer, as well. I just loved to do something with my friends, playing the sport and travelling with some guys from my practice group. We just had a fun time, playing club matches in the youth area, under 12, under 14, like four guys.
We are very good friends and we were just enjoying the matches and practice sessions together. Of course, I watched so many Grand Slams on TV, it was unreal. When I was in school, the Australian Open was on TV. They started at 1 in the morning. I was waking up at 5 or 6 with my mom, watching interesting matches."
