London : England new boy Chris Tremlett has admitted he still needs to be more aggressive despite a promising debut against India at Lord's.
"I'm quiet for a six-foot seven-inch guy, but there is some aggression in there.
"It's something I've worked on, to show a bit more intent with the ball and as a character," he told BBC Sport.
"I'll keep working on my body language. I'm not the sort of person who is going to swear at batsmen, but it will be the odd stare here and there."
The 25-year-old Hampshire seamer was a late addition to the England Test squad at Lord's but won a place in the final XI ahead of Stuart Broad, who was named in the original party.
Tremlett and Broad both played recently for the England Lions against India at Chelmsford and it was the latter who attracted more of the attention, with five wickets in the first innings compared to Tremlett's 1/40.
It is thought, however, that a hostile spell during a pre-Test practice session convinced the selectors to give Tremlett his chance.
"I was selected for the Lions which was a great honour and to be told in the second innings I was going to join the England side was amazing," Tremlett explained.
"I tried to show the England team how I have improved over the last few months."
He continued: "I didn't bowl too much in the nets, it was more in the middle. It was quite a nice bouncy deck and I was hitting it quite hard, so it must have impressed a few people.
"I was a little surprised but I was delighted to get selected, it's a great honour to make my debut at Lord's and hopefully there are many more to come."
One of the reasons behind Tremlett's impressive elevation to the Test ranks is thought to be encouragement from his county captain Shane Warne.
Tremlett failed to impress in the limited overs series Down Under, taking only one wicket in three matches.
"I was quite disappointed with my performances over there in the one-day series, but it was all positive from him, looking at where I want to go in the next couple of years.
"It wasn't exactly a boot up the backside, it was a reminder in each game to keep running in hard and not to give the batsmen anything.
"He'll be bellowing out from first slip to bowl fast and be aggressive. Sometimes I might switch off and for him to bellow out does me good."
Another combative international bowler who has been working with Tremlett is Allan Donald, who has taken over as England bowling coach for the remainder of the season.
"He said to make sure I was aggressive, if you are bowling a bouncer, bowl it like you mean it," said Tremlett, who is hoping to keep his place for the second Test at Trent Bridge starting Friday.
"We'll go into the next Test with the same positive intent as the Lord's game and hopefully beat India if the weather holds up," he added.
