The chart below displays the efficiency of forwards and midfielders playing in the English Premier League. It plots each player's shooting accuracy, in goals per shot, against their scoring rate in goals per game. The further to the top right corner of the graph the player is, the more efficient they are. All players in the EPL who have scored five or more goals are considered.
It is obviously swayed towards recent players or those who don't play that often. This makes Eastern bloc duo Dimitar Berbatov and Pavel Pogrebnyak the most efficient goalscorers in the league to this point.
