Sometimes when we are old, our hand shake on some occasions, we get restless, this would not be the case if we were younger, we have more time to react as well when we are young, some extra fractions of a second we have in our reflexes, plus we are also faster while moving and hitting shots on the run, if you are half a second earlier to a certain point on the court it makes a difference, you can run around your backhand and take the ball on your forehand if you are faster, isn't it ???.... Age matters everywhere in every single match.
I and all the Fed fans like
@TMF and many others who always consider Fed the GOAT we believe that if the ages were same of Fed and Novak then Novak's stronger return and his mental toughness (he is mentally tougher than other 2, nobody denies this) would not be a factor and Federer would pull it off vs Novak everywhere except the AO, this is our gut feeling but we cannot prove it. Things are what they are, FED is older and ALWAYS at a disadvantage, what looks like choking is actually induced by the age gap, he can choke once maybe, not so many times if the ages were same.
Nadal is the only person in history vs whose game Fed had some disadvantage, that too was because of the smaller racquet and age gap induced footspeed difference which which makes the backhand look weaker than it is
