I've gotten a lot better at defending recently. I switched my formation to have 2 CDMs and if I block the passing lanes, while using the 2nd man press, I'm more likely to win the ball back.
CPU defending needs to be downgraded. Bronze players play like gold and silvers play like Icons. The defenders never commit fouls. They also have 99.9% tackling success rate. Even on the rare occasion that they do miss, their ability to recover is lightening fast. I faked wide and he committed. I was turning to go inside, he already put in the second (successful) tackle. My players usually stumble for half a second when missing a challenge.
