Hamilton 'more fired-up than ever'

Mercedes driver Lewis Hamilton says he's "more fired-up than ever" ahead of the 2014 Formula 1 season opener in Melbourne, Australia.

The 2008 world champion endured a frustrating first season at Mercedes winning just once in 2013, finishing more than 200 points behind the champion, Sebastian Vettel of Red Bull.

However Hamilton, 29, says he has "grown" after a number of difficult seasons and believes 2014 could be the year when the team has the car to challenge for the title.
