Usually Goleada is scouting many players and almost every week superstar is found.
Superstar is a player that has very strong skills and talents. They are very strong on positions they prefer. On the other side their motivation is low when playing on the other positions and they perform weak there. Clicking on different positions buttons, the skills are changing to show the difference in performance.
The Superstars play fine on Top Leagues (100%), but they don't like to play in lower leagues too much - on second level they play with 90% of their skills, on third - 80%, etc.
Superstars love international tournaments and they could be a beasts there - on group stages they got a bonus of 5%, on Playoff stages - 10% bonus.
