If I get an yellow card I wait few minutes to see his rating,if it stay the same or drop I will change him,if goes up he will stay in (i know he will not get a double yellow 😉)
If, for example, a DC will perform bad,I will change him at half time and I will swap him with other defender wich has better rating (because most of times the player who came in will perform the same like the player he took his place,but many times when I'm doing this,I notice he plays better)
