Player symbols during matches

@qy0twn0z8nbt I am assuming that the symbols appear during H2H matches. 
To my knowledge, happy to be corrected, the red exclamation ❗️ mark appears if you are deemed to have held on to the ball for too long (like back passing and general time wasting). If it happens to much longer your players will pass or kick the ball away. This was introduced in s4 to curtail backpassing.

The amber text appears if a player has received a caution (yellow card). It’s not impactful unless you have an aggressive playing style.

Hope this helps.
