Afridi was the biggest hurdle between the bookies and spot fixing - Mazhar Majeed

According to this article, MM had told the undercover NOTW guy that Afridi was the biggest hurdle between him and the spot fixing. Some of the players who were partners-in-crime with MM were willing to lose purposly so that Afridi could be removed from the captaincy and Salman Butt be made captain.

No wonder a lot of people did not want Afridi in the team!
