Hamilton says he is stronger one year on

TOKYO: Lewis Hamilton says he is stronger, both physically and mentally, than ever and not about to blow his lead in the Formula One title race for a second year running.

The McLaren driver holds a seven-point advantage over Ferrari's Felipe Massa with three races left going into this weekend's Japanese Grand Prix.

Hamilton was unbeatable in the rain at Fuji last year but the Briton then squandered his lead in the final two races in China and Brazil, allowing Ferrari's Kimi Raikkonen to close a 17 point gap and snatch the title.
