Like i already said in your other post there is no fix to be made.
You can't change the dificulty in ultimate team, it is automatic.
The higher you go in league mode, the higher the difficulty gets. Thats the way it is.
If you can't handle the dificulty in league mode, you can always try to play some amateur and semi-pro tournaments to get some coins and card packages to sell.
Hi, this means that ultimate team is only for the good ones? ) ... it shoul be a mode, just like ultimate team for everyone to play.
