def/counters it's the set I use because :

1st step
- if despite my plans, I didn't manage to watch my game, at least it will be hard to loose it

If I 'm watching the game, I observe the stats.
If I have few tackles and oppo has many shots on target, I set them
or if I see many "live" scenes with oppo attackers.

or generally if I 'm winning a tough oppo or have the result which past me to the next round.

* but not to early (not before 30' because my players gonna be exhausted at the 2nd half with condition loss).
