Classy comments as expected from Federer. And it's true that winning 3 of 4 consecutive majors is an incredible achivement.
But when we are talking about single season achievements,
@NoleFam is right. Winning three majors CONSECUTIVELY and everything coming down to a pressure cooker final match in New York is different to winning 3 of 4 majors non-consecutively in a single season.
Even though Novak didnt win the GS this year we should still be looking upon this as one of the most special seasons ever.
It's crazy how many times he walked the tightrope in big matches and the fact that this run included the victory against Nadal in Paris. It was mental acrobatics from start to finish with this guy Djokovic and he really only showed how much mental burden he was carrying right at the end.
