Game is great and it can be even better if:
1. 5 substitute rule is implemented
2. International Country Manager Mode or Similar
3. Reduce the stars drop every season from 20 to 15%
4. Improve the rating based league placement system cause ppl are tricking the algorithm and getting easier league and others opposite.
5. Increase rests and treatments production from Facility.
6. Remove away rules system in 2 legged knockout matches. (New UEFA rule recently implemented)
7. Goal keeper clean sheet ranking just like others. (And if possible giving them certain reward just like goal scorer eg. 10/15%+ GK attributes)
