As I understand, club level, not manager level, has relationship to the quality of players representing with star.

Manager level is probably historical highest club (league) level of a manager. Club level is the current league level. Star is a method to indicate the relative quality a player to the club level of the manager in question.

As I still use old version, I have no knowledge if there is any new use of terms.
