Every match of a Chapter has its own set of objectives that need to be fulfilled in order for Managers to win points that put you forward towards valuable rewards. Please note that you need to complete at least one objective in order to earn points. Number of points per objective depends on the difficulty of each objective. Additionally, have in mind that you can complete the same objective multiple times, but claim the same reward only once. 
Bear in mind that objectives that ask of you to score goals, only count goals that occur during Regular or Extra time in the match. The goals scored during the Penalty Shootout do not count.

Bonus tips:
If your Seasonal Role or Playstyle boost is not activated, make sure to check if your player is placed in the correct position.
For the Seasonal Playstyle boost to be activated, the player's Playstyle needs to be unlocked (at least on Standard level) first.
Limited Training Drills help you reinforce your players through training. You can earn Limited Training Drills by completing Proving Grounds objectives and collecting points. Keep in mind that there are a limited number of times a drill can be used. Limited Training Drills only last for the duration of the season they were acquired in - unspent uses will be lost when the season ends.
