Editor's note: As the summer transfer window gets set to swing open, Gab Marcotti examined the biggest moves of the past five years and gave each a grade, factoring in fees paid, players' ages and performance as well as their contract situations. Part 1, which ran on Wednesday, looked at goalkeepers and defenders. Today, we look at the attacking end of the pitch.
Having looked at goalkeepers and defenders, let's turn our attention to more attacking players. I split players into midfielder, attacking midfielders and forwards. Naturally, there will be some overlap and, of course, sometimes a player's position will change over time.
