People fed's own age weren't beating him - but neither were 31 year olds beating him either. Duh! What sort of sophistry are you trying to run past us?
Not to mention that Ljubo that couldn't beat his age peer Federer whom he met in a few finals, turned around and at 30-ish beat one of the "strong era" people, Nadal, to go on to win Indian Wells.
Why do you take one isolated match? or do you expect Novak to win all their encounters? what amount of bullshit.
And ivanban is right, as everyone knows. Even Pat Cash said that the best djokovic he saw in 2011 is even better than peak Federer because he had to face much stronger opposition.
