He has nothing more to prove to anyone after haunting batsmen for more than 15 years in international cricket and Harbhajan Singh believes that his “tried and tested” strengths are the ones he will rely on as he prepares to lay his hands on a record third world title.

Harbhajan was named in India’s Twenty20 squad for the Australia tour, which will be one of the last few events ahead of the World Twenty20, to be held in India in March.

“I don’t think I need to experiment with anything like carrom ball or so. I have my core strengths which is the off-break and the doosra. It has given me results in the last 15 years and no one can take away my 700 plus international wickets from me,” Harbhajan said when asked if he would unleash any special delivery with the World T20 round the corner.

He is perhaps hurt at the omission from India’s One-day squad after an impressive performance against South Africa but he would not speak a word on not being selected in the side.

Against Proteas he had six wickets in four matches with an economy rate of less than 5.50 per over.

“I have had a very good ODI series against South Africa. Right now, my focus is to win the World T20 for India. I have two World titles (T20 in 2007 and 50-over in 2011). So it would be really special if I can contribute for India in pursuit of a hat-trick of World titles,” said Harbhajan.
