Indian off-spinner Harbhajan Singh today lashed out Mathew Hayden terming him the biggest chicken hearted cricketer he has ever seen and said the Australians remarks against him for missing the Nagpur Test were a lot of crap to sell his book. I dont know what these Australian cricketers are up to? Even Ricky Ponting wrote a lot of crap to sell his book and now this guy Hayden is doing so, Harbhajan fumed while giving his reaction to PTI. The former Australian opener in his autobiography Standing My Ground had said that erstwhile Indian captain Sourav Ganguly and Harbhajan chickened out after having a look at the bouncy Nagpur strip during Australias tour of 2004. He had even expressed his surprise in the manner in which Harbhajan had food poisoning on the eve of that Test which Australia won convincingly. Who is Mathew Hayden to judge Harbhajan Singhs calibre. I dont know what he is smoking these days. Probably he was in some kind of trip when he wrote all that rubbish. Should I now give Hayden some money to keep quiet? If that wasnt enough,Harbhajan said that he is still willing to bowl if Hayden has the heart enough to face him. This is an open challenge. Whenever and wherever Hayden wants me to bowl at him,I am ready. Does he have the courage to face me. Because,whenever I have seen him bat against me,he always had a petrified look. Just check the record books in case you want to know how many times I have got him out. Referring to Haydens term of Greentrackitis,Harbhajan said,I have scored half century even in Australian soil. May be Hayden has this habit of conviniently forgetting the achievements of Indian cricketers. At the end of the day,he doesnt have the qualification to judge the calibre of Indian cricketers.
