Hi Cobh....
I don't tend to worry about my SoT ratio, but against harder opposition I have found that putting an extra DMC between def and mid, having wingers and fullbacks on an offensive mode (dark arrows up) as well as same for lone striker (4-1-4-1).
Also, in-game I will swap wing players (if both are able to do so), and use mostly Possession in the bonuses.
Often I will then go to a more attacking formation around 80 mins, by losing a MC and replacing him with an AMC, and going 4-1-3-1-1...spreading your three midfielders evenly with one in middle, one wide each side.
Don't be afraid to go out all attack in these last "10 minutes" either, and try the Conditioning bonus for the same period.
Good luck!
