Here is What Federer said about this glorious Year :
"Regrets, I don't have any, But maybe losing to Haas and Donskoy ended up haunting me. I had match points in both matches. It's not like I didn't try. If I miss out because of that for World No. 1, then maybe I was unlucky. But I also did win matches in Miami, saving match points against Berdych, other matches throughout the season that could have been gone either way as well. In Australia, it was Nishikori. You name it. Things could have turned very quickly much earlier.
