The delusion of Rosberg

As part of race build up for Malaysia, it was put to Rosberg that he didn't work long into the night like Sebastial Vettel does.  His answer was that some drivers have natural talent and some have to work harder at it.  Am I making the wrong inference or does he seem to think he possesses more natural talent than Vettel?  What an outrageously egotistical, and completely deluded thing to say!  I have always seen Rosberg as being a little boy playing at racing because 'Daddy' did it, and this has done nothing to change that view.
