The higher your Club Level, the bigger the stadium your players get.
Not only will the stadium in the background during Team Training grow, but also your home stadium in the background of the Home screen.
Level up your Club and get a stadium that befits your rank as a big league football club.
The stadium will grow when you reach Lv. 10, 20, 40 and 60.
*If your Club Level exceeds one of the thresholds above before the 20 December maintenance, you will see the respective stadium after maintenance ends.
