Here I can see two things.
One is a classic "troll" action of the game, when oppo loose a player from a red card, his team scores.

The other one is the behavior of a token buyer/farmer, who believe that if he has a 5-6-7* players team, can win every weaker team.
The most common mistake is that this manager using only attack and in some games oppo defenders stop the attacks and he kills you with counter attacks (specially when he's playing with AM vs no DM).
