The veteran off-spinner yesterday staged a comeback to India's ODI squad for the tour of Zimbabwe after a gap of four years. "Obviously, I can't tell you how happy I am that I will be wearing this blue jersey again. I don't know anything apart from playing cricket.

"This is all I have done in my life and I am happy that I can again try and give my all for India," an excited Harbhajan said in an interaction.

Asked if his decent outing in the one-off Test against Bangladesh has prompted the one-day recall, Harbhajan said, "That the national selectors would be able to tell you. For me, the aim was to give my 200 per cent in India jersey after a comeback. I had prepared hard for that match.

"I believe cricket has a similarity with academics. A student studies day and night for his exams after 10 months.

"The only difference is for a cricketer, there is an exam every third day and you have to be well prepared for every exam. "I feel that Zimbabwe series is another exam and I am studying hard to excel," the Turbanator said from his Jalandhar residence.
