In Football Associations, Managers can earn division and tournament rewards.

Note that for both types of rewards your FA needs to have at least 4 members to be eligible. Additionally, Managers need to be in the top 8 in the previous season’s League in order to be able to claim the rewards.

In case you missed tournament (weekend) rewards note that:
You need to join an FA before the tournament matchmaking is finished. Otherwise, you won’t be able to participate in that weekend’s tournament and you won't be eligible for the division rewards.
Only Managers whose FA Points Multiplier was not 1 or 0 are eligible for the tournament rewards.

Throughout the entire season, you can check in the "Associations" menu whether you are eligible or not for the rewards.
