hi @trueblue9877, what problems have you noticed when watching the games? Or are you just after general ideas?
My initial thoughts are good teams might press your defense and playmaker more, so maybe look to get the ball forward as quickly as possible. Maybe get rid of play out of defense and take off the advanced playmaker if he is getting marked. Maybe also consider more conservative fullbacks. But without having seen a game with this I am not sure.
It also seems that a few of your players are not suited to the roles (just looking at the stars). Now I know we can't completely trust the stars, but they are pretty low! Is there a reason for that (like people playing out of position)?
