Pakistan coach Mohsin Khan supports technology in international cricket to rectify umpires' mistakes

Simon Taufel of Australia, one of the best umpires in the world, had three of his decisions overturned by the television umpire on the first day of the third and final test between Pakistan and England on Friday.

Pakistan s Mohammad Hafeez and Azhar Ali and England s Eoin Morgan all had to walk back to their changing rooms after Taufel initially ruled in their favor.

Khan says, "one bad decision can change the whole scenario ... so I am totally in favor of this DRS system."

Khan also believed that technology is "improving a lot," and he would have loved having the system in place when he was an opening batsman for Pakistan in the 1970s-80s.
