Mitchell Johnson, a prime architect in Australia's second Test win over India in Brisbane, has reinforced the importance of "psychological warfare", arguing it is imperative to intimidate the opposition.

In a new DVD titled 'Mitchell Johnson: Bouncing Back,' he has elaborated on many of the recent key cricketing issues, including overwhelming England last season to win the Ashes.

Johnson emphasised how critical to the series victory was the team plan to intimidate the England batting - in particular the tail. He also explained how he was also grateful that he injured himself while in South Africa in 2011, as it made him a better bowler.

When talking about the mental approach, Johnson said: "Sometimes we say stupid things when we're out there.

"Sometimes we try and say things that hopefully get into the batsmen's heads a little bit. We try to get them to think about their feet, or just let them know you are going to bowl another short ball. It's all mind games.

"Sometimes it might look a little different on TV. It might look as if we're going a bit too hard at each other, and sometimes it could be a bit over the top. But we're always trying to stay inside the guidelines.

"If you can get into someone's mind by speaking to a batsman and tell them that their feet aren't going anywhere, hopefully they'll start to think about that. You then bowl a short one at them, and you're in their head. I love that part of the game. I think it's great. And I don't think it's ever going to stop."

Johnson said the bowling attack decided to be ultra-aggressive at the start of the Ashes series. Frailties quickly emerged in the First Test in Brisbane, when Johnson dismissed Jonathan Trott, taking advantage of some perceived weaknesses shown in an earlier series.

"The plan was to go hard at him. We'd knew that he'd step across a long way, and the way he plays the short ball… he struggled in that one day series earlier in England. That was the plan to him. The delivery was probably a bit wider than I wanted it, but he pushed the bat out there because he was in a bad position. It [Trott's dismissal] was definitely a crucial point in the game."

Michael Carberry was the next target.

"I didn't want to go around the wicket. I was a bit iffy about it. Michael (Clarke) was really keen on me to do it, to change the angle, because he was just letting balls go outside off stump. He was really patient at that stage. So I came around the wicket. We had the field set for the short ball.

"The first two balls I went hard at him, and then one went across chest high. He went to play and leave, and found the edge.

"That definitely sparked a bit of panic in their dressing room. Our goal throughout the whole series was also to go after their tail. Once we got their tail in, I don't think they were too keen on it. Going at Stuart Broad's body didn't really give him a chance to move. Having that field set, it was definitely playing with their minds. And that stayed with them throughout the whole series. They didn't want a bar of it."
