There seems to be a flaw that makes the event of attackers penetrating the midfield and defense to score goals occurring way to much. Defenders, especially central defenders do not seem to be able to stop them as they should, and the GK does not stop enough shots. Attackers seem to penetrate through the defense way too easily by running with the ball, even lower quality attackers versus higher quality defenders, so as to make one-on-one situations and score. This also explains why so many defenders have got poor ratings lately.
Something has gone wrong after the recent changes or updates in this game. Lower quality teams or players are scoring more goals than expected.
