LONDON (Agencies) - A day after Salman Butt and M Asif were convicted for spot-fixing, former England skipper Michael Vaughan suspects that a Test match against Pakistan in 2000 might have been fixed. Vaughan said Pakistan had surrendered from a strong position and now he is forced to think if the home players played genuinely and even at that time the same thought crossed their minds. "I now look back on matches I played in and wonder if strings were being pulled behind the scenes. For instance, go back to the Test we won against Pakistan in Karachi in December 2000. "They collapsed from a strong position to leave us a small total to chase, which we did as night descended. It was a very surreal atmosphere and I remember feeling that there was something not right about it at the time. Was it just a dodgy wicket or were there other forces at play?," Vaughan wrote in his column for 'Daily Telegraph'.
