MUMBAI (Agencies) - Former Pakistan captain Wasim Akram on Saturday ridiculed Shoaib Akhtar and his controversial autobiography, which has made several tall claims, saying that the pacer was a "problem" when he was an active player and remains just that even in retirement. Akram pooh-poohed Shoaib's claims of making Sachin Tendulkar uncomfortable with his pace in the Faisalabad Test in 2006 and also rejected some of the other allegations he has made in the book titled 'Controversially Yours'. "I remember one of Sachin's knocks in the Sialkot Test. It was the fourth Test and the wicket had lot of grass, I was 22 and Waqar was 19 and we were very fast," Akram recalled. "Waqar hit him on his chin and he came back after taking treatment and scored a 50. If a 16-year-old can't be scared, I don't think any batsman can be scared. It hardly matters what Shoaib says," Akram said. Akram said Shoaib was just trying to sell his book with tall claims and also rejected allegations that he tried to destroy the tearaway pacer's career.
