Lewis Hamilton defiant over Rosberg

Lewis Hamilton has shrugged off Nico Rosberg’s threat that he is feeling back to his best — insisting that is still not good enough to beat him.

Reigning world champion Hamilton has enjoyed a fine start to his title defence, winning three of the opening four races and finishing second to Sebastian Vettel in Malaysia.

That gives him a 27-point lead over Mercedes team-mate Rosberg — the man with whom he was enveloped in a bitter title tussle for much of 2014.
