Love it, when it happens like that :)

Greetings.
Before uploading the screenshots, I'd like to mention my feeling for the result - players were at 65-70% condition.
It seems it does matter, since I couldn't get enough time to "heal" them. Or, maybe it's a troll result, not certain as of yet.
My mentality at that match was :
Started Normal till the first goal, then switched to defensive.

Down both flanks, later switched to mixed, after the first goal, and motivated MC ( arrow up ).

Mixed passes with possession bonus. Switched to short after the goal, again with Possession.

Counters - ON. I know it's a mistake, when using Possession, but it works for me ( 48 matches unbeaten, 45 wins ).

Pressing - Low
Tackling - Normal
Marking - Always Zonal, I find it better, and flexible
Offside - OFF

Possession bonus should not be used when playing defensive, some will say. Yes, I would agree, since the idea behind the Counterattacks is to intentionally GIVE the ball, in order to steal it back, so a counterattack can occur.

His mentality was :
Normal
Middle
Mixed
No counters

High pressing
Normal tackling
MtM marking
Offsides - ON
Yes, I know because I see how his team was moving across the field.
Now, the screenshots, and the question : Where did I made a mistake, why the red card ( DC+DMC 106%, regularly trained 19y.o. ). Morale was very good, not superb, but very good to every player. Should I try 4-5-1 flat, 4-1-4-1, 4-4-2, or should I try again with 4-5-1V ( I have another DMC, weaker, but will do the job )
