Herminator's true value
But just how much is he worth to the club in terms of points each year? Warwick University's Decision Technology Group have developed a way to compare the number of points that a club might expect to gain or lose by purchasing or selling a player. The method involves looking at the actions (passing, dribbling, shooting and so on) of indvidual players and relating those to outcomes of games.
According to their calculations the Herminator adds 2.5 points a year to Charlton's tally. This ranks him third among Premiership left backs with Boro's Frank Queudrue in the lead followed by Heinze at United.
Ashley Cole only adds 1.9 points a year. If Cole leaves the Gooners, they can keep their hands off Hreidarrson.
