If you played Champion of the fields,you will remember that there were two modes to play which was the normal pVp mode and the coach.
This game mode will be an unlockable feature which I believe will be unlocked once a player reaches level 5.
In game,the players would be able to implement their tactics for both the team and the players.
And as for ranking and rewards,the season data would be available to see so that you can see you and your rivals' progress in the pursuit for the best rewards.
If you are a fan of Football manager games,you ought to be excited.
