Lewis Hamilton has come out with some advice for Sebastian Vettel, urging the reigning Formula 1 world champion to show true leadership at Red Bull.

The Milton Keynes based team has been pushing to emerge from its pre-season crisis involving troubled engine supplier Renault.

But at the same time, German Vettel – the reigning quadruple-consecutive drivers’ world champion – has been struggling simply to keep up with his fresh-faced new teammate, Daniel Ricciardo, following the sport’s V6 rules switch.

Further up the grid, Hamilton and his Mercedes have been dominating, but in an interview with Bild am Sonntag newspaper, the 2008 world champion commented on Vettel and Red Bull’s plight.
