The 22-year-old and world No. 209 Marc-Andrea Huesler was one of the two hitting partners chosen for a two-week practice with Roger Federer in Dubai this year in April. The other partner was the 19-year-old and world No. 726 Jakub Paul.
Recalling those training sessions with the 20-time Grand Slam winner, in an interview to Blick Huesler said: 'It was very beautiful, besides impressive to see how Federer trains. From one side you see that you can play, from the other one that there is still a long way to go to get to the top', said Huesler, who also trained with Federer at last year's Swiss Indoors in Basel.
Despite English is not one of the official languages in Switzerland, his parents made Huesler grow up bi-language. 'My mother travelled for a long time in the United States: that's how the choice was born, for me and my sister.
She speaks with us in English, with my father in German', he said. Huesler is 196cm tall, which is much more than Stan Wawrinka or Federer. Sometimes it can be an issue when travelling. 'Especially in the air flight', he admitted. 'I always try to find a free space in the emergency side.
At the beginning it was a problem, then I got used to it.' At this week's Swiss Open in Gstaad, Huesler defeated the former top 10 player Nicolas Almagro in three sets, 6-7 6-3 7-6, then lost to the Argentina's Facundo Bagnis 7-6(10) 6-1.
