New Delhi, Oct 8 : Injury and age is fast catching up with him, but Australian speedster Brett Lee says the tag of "world's fastest bowler" is too dear to his heart and he will do whatever it takes to maintain his lethal pace of 150 kmph.

The last couple of seasons have not seen Lee at his best with injuries keeping him out of the Australian team.

Lee, who will be turning 33 next month, has led the Aussie bowling attack with aplomb after Glenn McGrath's retirement. In fact, Ricky Ponting missed his most potent pace weapon during the Ashes loss this summer when the Australian attack did not have that threatening look a fit and strong Lee brings with him.

Lee got back to the groove in the 6-1 ODI series win against England and then the Champions Trophy triumph in South Africa. Now the speedster is looking to return full steam in the Champions League Twenty20 for his provincial side New South Wales Blues before getting back to the Test team against the West Indies.

Lee for sure is not going to cut down on his pace.

"I have worked hard to bowl consistently at 150 kmph. I enjoy being the world's fastest bowler and it means a lot to me. I love bowling fast. If you mean that I bowl outswingers at 130 kmph, that's not going to happen. I am not going to compromise on speed. If I am not able to bowl at 150 kmph, then I will have to think of a plan B," he said.

"Fast bowling is a tough trade. In fact, it is the most difficult job in cricket, but when you hit the in-swingers right it's very satisfying. There's nothing better than bowling a fast inswinger to a batsman. The pitches are now more conducive to fast bowlers."

Lee said that the Champions League would be a stepping stone to retain his Test berth.

"I am happy with my form in England and South Africa. I am into my 30s but still have the hunger to bowl fast. I have the fire in the belly. I always judge my body on my speed. I know when I am hitting 150 kmph and I am getting back that feeling now. The Champions League will be another stepping stone for me to get back to the Test side in Brisbane (against West Indies)."

Asked about the Australian bowling attack, Lee said: "Mitchell Johnson is going from strength to strength and the others boys are also developing well. I think we have got a good mix of youth and experience."

Lee said that the upcoming ODI tour to India will be tough.

"It is always challenging to play in India. We go hard at each other as soon as we cross that white line but after the game is over, we are friends. I love touring India and so do other Australian players," said Lee. (IANS)
