Roger Federer's return in a training session in Dubai on Saturday left Fernando Verdasco impressed. The Spanish player was filming a video and he caught an amazingly powerful backhand by Federer while getting a serve back. 'Oh my god, so much energy on this return Roger. Oh my god', Verdasco said. Federer heard it and he started laughing. Roger and Fernando will face each other on Wednesday in the second round of the Dubai tennis tournament. In press conference following his win over Thomas Fabbiano, Verdasco spoke about how it feels to play doubles with Philipp Kohlschreiber: ""He is German, I'm Spanish, so mentality wise we are pretty different. In Spain we're a little bit more crazy, Latino-wise. German are more like mental, focus, everything super strict and all that. But he's a good guy. I mean, I had a super good relationship with him for many, many years. I don't know if we are the same age, but close to each other, maybe one year or whatever difference. We have been on the tour together all our careers, 15 years, many years."
