Tremlett: I'm naturally aggressive

England seamer Chris Tremlett believes he has finally turned into the aggressive, snarling bowler that everyone wanted him to become when he made his Test debut four years ago.

Tremlett will lead the attack in the second npower Test against Sri Lanka at Lord's on Friday after playing a key role in the downfall of the tourists in last week's first match in Cardiff.

The 29-year-old took four wickets against India on his debut at Lord's in 2007 but was dropped from the England squad after the series, and said on Wednesday: "In 2007 I tried to be quite aggressive when I played against India. Maybe that was a bit forced a little bit, it didn't come naturally."

He added: "Now fast bowling and being aggressive is something that comes more natural to me and I have grown as a person and a cricketer.

"I went through a spell where I was in and out of the squad. Now I'm in the team and I am a lot more experienced, a lot more hungry, I know my game and body a lot better."

Last week's victory in Cardiff was all the more remarkable given that a draw seemed inevitable after the Test was hampered by rain.

After declaring on 496 on day five, with a lead of 96, England skittled the visitors for 82 inside 25 overs in a blistering afternoon of clinical bowling.

Tremlett, who took four wickets that afternoon, thinks the win proves Andrew Strauss' men have a killer instinct that he hopes they will be able to repeat over this weekend to wrap up the three-match series with one game to spare.

He said: "It was a dull couple of opening days in Cardiff but we came out in that last session and showed how good we are as a team.

"We showed that we are a team that aren't afraid of kicking the opposition when they're down. That's what we'll be looking to do in this game."
