KARACHI - Former Pakistan captain Shahid Afridi, who announced his retirement from international cricket soon after the World Cup to protest the working of the Pakistan Cricket Board, says he will decide on comeback after a month. "There is a lot of pressure from fans and friends to come out of retirement, but I will wait for things to improve. I will take at least a month to reconsider my decision." Pakistan will take on Sri Lanka in a full series in the United Arab Emirates, starting October 18. Afridi said he was not compromising on his form and fitness. "I am training hard and focusing on improvement with both the bat as well as ball." Meanwhile former Pakistan captain Shahid Afridi supported the tearaway fast bowler's claims that Sachin Tendulkar was scared of his pace, saying he was a witness to the master batsman trembling at the sight of Shoaib. In his book " Controversially Yours", Shoaib wrote that Tendulkar was scared of his bowling, a comment that has caused furore across the border, forcing publishers to cancel all launch-related and publicity events. Asked about Shoaib's claims, Afridi said: "Shoaib is telling the truth. Tendulkar was afraid of him and I saw Tendulkar's legs trembling while facing his bowling."
