"Easy."

That's how Kimi Raikkonen summed up his victory at Sunday's Formula One season-opener at Melbourne.

The Lotus driver came from seventh on the grid to claim maximum points and beat Ferrari's Fernando Alonso into second with reigning world champion and polesitter Sebastian Vettel third.

Raikkonen, nicknamed "The Ice Man", kept his cool throughout to see off the attentions of Alonso, the man who replaced him at Ferrari at the end of the 2009 season.

And the 33-year-old believes his opening day triumph could shape Lotus' season ahead of next week's Malaysian Grand Prix.

"I made a few places at the start and then had a good battle with Lewis [Hamilton] before I eventually managed to get past," Raikkonen told his team's official website.

"After that it was quite simple; probably one of my easiest wins.

"You can't start the season much better than winning the first race and of course we hope we can be fighting at the front of the Championship.

"But there's a long way to go still and we need to keep pushing hard all the way through.

"I think it will be two or three race before we really see where all the teams are.

"Hopefully we can qualify a bit better at the next race and have a similar performance."

Raikkonen has been here before.

Six years ago, wearing the red of Ferrari for the very first time, Raikkonen illuminated Albert Park with a debut victory which would catapult him towards his first and so far only, world title.

Time has passed but the class remains. His sole victory last season came in the 18th round at Abu Dhabi, while he also claimed second place on three separate occasions.

Two years away from the sport, where he spent time racing in NASCAR and the World Rally Championship, appears to have done little harm to the confidence of a man who finished 74 points off champion Vettel last season.

With all the focus on whether Ferrari can finally end Red Bull's dominance and whether Alonso can finally overtake Vettel, Raikkonen has faded into the background.

It is not a position he would be unhappy with. Raikkonen has always been a quieter man, one to do his talking on his track and away from the media and public opinion.

Last year's third place finish in the drivers' standings at least gave encouragement that Lotus was on to something, although it is far too soon to say whether its challenge be sustained over an entire season.

At least at Melbourne it proved the real deal, with Raikkonen's two-stop strategy enough to see off his rivals, who elected to head into the pits on three occasions.

"We've had a quick car all weekend and there were no issues with it either, so we could just focus on trying different things and getting the setup how we wanted," he added.

"I'm really pleased with how the car performed here; I felt like I could push when I wanted to and it was never too difficult to find the speed.

"The team got the strategy perfect; apart from maybe Force India I don't think the others looked like they could do the same thing."

While Raikkonen managed to hold off Alonso's challenge, the Spaniard is remaining philosophical after Ferrari managed to finish ahead of rival Red Bull.

"Finishing ahead of the Red Bull tastes like a win, even if we know that despite today's race result, they are still the quickest," he told reporters.

"Now we can expect another weekend (in Malaysia) with very changeable weather and one that also puts a lot of stress on the cars from a mechanical point of view and on the drivers, from a physical one.
