Hamilton feeling the F1 pressure

Lewis Hamilton gets his world title defence under way in Melbourne on Sunday and is a man under pressure. But as far as he is concerned the pressure is all from himself.

Having won the 2008 season in dramatic style the World Champion isn't satisfied and wants to win it again in 2009.

It is going to be a tough season repeating his stunning drive for Vodafone McLaren Mercedes last year, especially if the results of early testing are taken into account.

The new McLaren seems to be suffering from the raft of rule changes for the 2009 season and have found themselves at the bottom of the time sheets during testing. Hamilton admitted it is going to be a long hard campaign but believes he can be better, faster, sharper and more consistent than last year.
