So if I have a 1* player at the end of the season (don't ask me why I would have him), next season would he be kicked out and sent home?
No, he would still remain a one star, but would just take longer to get to 2* as he's that poor (I saw one team that had a 1* player with a quality of 12(!!!!!!!!!!!!!) in his squad. They were level 5).
Rhondda Rovers (The Rebirth) - Season 5, Level 3
Career Progress:
League Titles - 3 Cup Winners - 1 Champions League Winners - 1
