Did Federer say that? It was not in quotes. I thought it was your addition. Source please.
Federer did indeed say that.
Federer was attempting to become the first man since Ivan Lendl 25 years ago to win a hat-trick of season-ending championships, and his seventh overall.
"Maybe there's a bit of regret because I had the lead twice before him," the 31-year-old admitted in defeat.
"At the end of the day that doesn't matter, you have to get over the finish line in the set and then obviously the match. He was better at that today.
"What he does well - even in defence he stays somewhat offensive. That, I think, is what separates him from the rest a little bit."
