Hated the demo at first, especially the defending; it was damn near impossible for me to figure out.
Went from my normal pro difficulty down to semi-pro, still struggled a bit.
Last few games I figured the game out, started scoring goals actually and being able to win the ball.
Also, pulled this cheeky goal off:www.youtube.com/watch?v=Y-eF5apXQEQ&feature=player_embedded
For defending I still haven't completely figured it out. Sometimes I just manually contain a player using L2, sometimes bring a second defender over with R1, sometimes try standing tackles, and sometimes use the contain feature with X.
It seems like most times I'm just waiting for the ai to make a mistake in order to win the ball, very rarely can I go and just steal it away.
I also thought it was bad at first that the ai just contains you, giving you way more time on the ball. But it's actually better than 11 where you were instantly pressured. It's easier to hold the ball, look for open space or an open man, switch play to the other side of the field, etc. But sometimes it's too easy, like there were quite a few times where the ai let me basically walk into the box with aguero and didn't even pressure me at all.
