Lewis Hamilton says his motivation to win the championship has doubled this season and insists his level of self-discipline is higher than ever before.
The Mercedes driver lost out on the championship to teammate Nico Rosberg last year and this season looks set to go up against Ferrari's Sebastian Vettel in a battle for the title. Speaking after he lost the opening round of the season to Vettel, Hamilton said he would return to his Monaco home between races to ensure he is fully rested ahead of the next round in China.
"I had a fantastic fight the last few years and obviously last year was the closest that I had," he said.
