I've developed a simple web app called The LFC Goal Machine that plots a player's age against the league goals that the player scored in a top level season. The app knows about every LFC player who scored a top level league goal in more than one season, from 1894-95 to 2014-15. You can use the app to compare players across different seasons and eras. Simply select one or more players and take a look at their graph. You can play with the lfcgm app at lfcgm.lfcsorted.com.
