In an interview as quoted by ATP Felix Auger-Aliassime was asked who is the toughest opponent he has ever faced. The Canadian said: "Probably Roger Federer. He is the best or one of the best players ever. I had the chance to train with him in the pre-season and it was definitely the toughest training I had in terms of intensity, accuracy...
The way he plays is very difficult to face." Asked what was his best moment on the Tour, Auger-Aliassime replied: "When I faced Vasek Pospisil in Indian Wells. I was playing the qualies to reach the main draw in a Masters 1000 for the first time.
People were very excited, it was at night." Asked what's the biggest advice he has ever received, Auger-Aliassime replied: "A coach gave me it, when I was 13 years old, before facing Frederic Niemeyer, my compatriot.
I used to focus on winning matches and results, and he was the first coach who told me, Focus on seeing the game level you have, and it will make you win matches." Asked what's his favorite surface between hard and clay, Auger-Aliassime concluded: "I think 50/50.
I think that today's tennis has players like Zverev. We can ask the same question about him, and it's difficult to answer it. He has won Masters on hard surface, on clay, and even on grass. So it's a little bit of my style, too.
I think I'm able to play on all surfaces. Both are very nice to play on. I believe, though, that on clay the game is more varied and more pleasant to play and to see it played. I like very much this surface, and I think I'm able to win on both kinds of surface."
