I think ICC should stop the concept of umpire’s call. It is visible that in the current tour of west indies , Sri Lanka got a lot of decisions go against their way. Due to umpire’s call option , umpire has the ability of going in favor of one side. If an umpire is biased , he can all ways give decisions in favor of one side. So even if some one reviews it, it can not be overturned if it is fulfilled the criteria of umpires call.
Recent tour of west indies showed umpires giving tight calls in favor of west indies. So reviews failed because of umpire’s call criteria.
Please ICC ban umpire’s call option.
