[High possession and passing completion]

Well look at the full match, no wonder they are calm and make every pass. There is almost no press on the backline, keeper and defensive midfielders. Ive seen situations where a AI defender is on the ball and just standing still, and my players are also standing still 20m away from them lol. He just stands there for 5 seconds and them pass the ball to the other CB.....

[AI Possession massive]

This also happens with AI vs AI games. Look at the stats of big teams playing at home vs small teams. The small teams have the better possession and pass completion %. IMO this ruins the game right now. To win these games when youre the favourite you have to play two strikers and very attacking to get atleast some press on the AI defence. You can also do this because these AI teams have no interest going forward or to counter.

[Bug with Crosses]

True, have the same issue, all the crosses go high and back post.

[High possession and passing completion]

Reason for this is AI teams will just pass the ball between keeper, defenders and maybe defensive midfielders. Your team will not press, you can set whatever pressing settings you like they will just not press them (watch on full match). Therefore AI teem keeps possession and high % pass completion

[Individual markins keep failling]

Agree, this has been a problem for so long. I don't understand why SI needs more examples on this, don't they test their own game, as OP stated this is very easy to reproduce?

[AI Possession massive]

I just had the same, playing as AC Milan at home to Cagliari. On extended highlights half way tru the first half they had 75% possession. I decided to watch the full match and saw them playing vertical passes between the three centerbacks, over and over again. My attackers were not pressing. Changed the line of engagement to much higher and put trigger press on the three center backs in the opposition instructions. Nothing changed, my players refused to press the centerbacks.
