I am not the best fifa player around, but i have noticed high scoring games also. A lot of breakaways given up on both sides.
What i have found that works to some degree, is to go into each igm#1 of each team and reduce their attack mode to half. If you notice every team is in full attack, when you go under the team management. this does not make sense, no matter what team you are.
I am playing in the professional mode.

thanks for the suggestion I will try it

If you are playing against the computer, wouldn't it automatically reset?
Sounds like it's worth trying though.
