Australia paceman Peter Siddle has no intentions of calming himself down when the 2009 Ashes series heads to Lord's.

The 24-year-old Victorian, in his first Ashes series, took only two wickets in the drawn opening Test in Cardiff but certainly kept England's batsmen on their toes with a fiery display - hitting tail-ender Graeme Swann more than once and even having a brush with Stuart Broad as he ran down the wicket.

Captain Ricky Ponting, who again looks set to be without veteran quick Brett Lee because of a rib injury, feels there is plenty more to come from Siddle.

Having seen Lord's, home to the MCC, close up at today's practice session, Siddle cannot wait to get stuck into England once again.

"It is just part of me. I like to go about that kind of stuff," he said.

"Swann was pretty confident in the first innings and we probably didn't test him out as much as we would have liked.

"In the second innings, we had that opportunity and although the wicket was a bit flat, if you dug in you could have a good crack.

"We found that was a bit of a weakness, but he toughed it out and he stuck around for a while.

"It was just good fun.

"We will see how we go about pitching another one up to him in the series, but I am sure he will have to wait a few deliveries."

Siddle continued: "That is when I am bowling at my best, when I am fired up and charging in.

"The sooner it happens the better it is for the team.

"But I am very relaxed off the pitch, very laid back, nothing really bothers me. I just go about my business and just be ready to go."

Siddle - who has earned the nickname 'Sid Vicious' - believes he takes strength from such an aggressive approach, as he showed in the recent series against South Africa when he claimed successive four- and five-wicket hauls.

"It's just been a part of me, it gets me going, I feel more at home when I am in that sort of state," he said.

"It took me a while to get into it in the match, but hopefully this match I will liven up a little bit earlier and get amongst it.

"In that second innings I got comfortable for my good rhythm and charged through the crease.

"I am feeling confident and really fit and strong for this match."

Lord's has proved a happy hunting ground for Australia, with their last defeat there to England coming way back in 1934.

Glenn McGrath holds the overseas bowlers record with figures of eight for 38 during the 1997 series.

Siddle would like nothing more than to make a similar impact this week.

"It is amazing. Growing up, there were a few little dreams... an Ashes series at Lord's was one of them.

"It is just amazing, the history and tradition and running out there on that first day will be great."

Australia were left frustrated on the final day at Sophia Gardens, where England batted out to earn what had looked an unlikely draw after the visitors posted a commanding 674 for six declared.

While disappointed the tourists were unable to press home their advantage to take the lead in the series, Siddle knows plenty of cricket is left this summer.

He said: "It is an Ashes series, there are always going to be ups and downs, and little niggles here and there. It has always happened in the past and it is part of it I guess.

Overconfidence can be lethal

"But we must not get too confident. We have got to stick to the plans, execute well and see how we go."

Siddle added: "It is tough being out there, very taxing on the body to keep on trying to stay up to take those wickets.

"But it is Ashes cricket, so England are not going to come and not be ready for this match. They are going to be out there firing."
