I don't know what is happening, but my defence is very bad lately.
These last days I can't have a single win, despite having always 10-30% more possession than the opponent and a bit better team.
My defence takes goal at every opponent's goalscoring opportunity, but the opponent's defence stops more than half of mine.

The main difference here is that I have 3 defenders (all Centre Backs) and all my opponents had 4 (classic one).

So, my question is...
Have you guys noticed defences with 3 players getting more goals than normally??
I know bad periods come and go, but I'm just asking if anyone has noticed this, so I can throw away these doubts.
