Lewis Hamilton will try to lay down a marker in this week's season-opening Australian Grand Prix as he sets his sights on beating fierce rival Sebastian Vettel to a fifth F1 world title. Mercedes's reigning world champion and Ferrari's Vettel can both join the legendary Juan Manuel Fangio as five-time world title-holders this year, second only to Michael Schumacher's seven. Vettel swept home in last year's opening race against Hamilton in Melbourne before the British ace went on to land the championship with two races to spare from the German.
