Broad personal training question

So training for a few (yes a few) team and individual sports pursuits. Just your usual gaa, soccer and stuff

I'm good at training for whatever sports is being trained for

In a nutshell what I'm looking at focusing most on is where opponents (team or individual) compete basically with nothing to lose/underdoggish type.

Imagine a Diego Simeone team, Jack Charlton "put em under pressure" team or opponent. Basically whatever it is that's not concerned about the skills

If it not for these type of teams or individuals the skillful team or what ever would always win

What training should I be doing that I can continue to be at myself regardless of what may come

What type of training is it that make these type of opponents??

Something?? Anything that I could be missing out on other than your usual training routine?? Or even a way i should be mixing up training routine

This is purely a training thing and includes everything apart from the dealing head on with the type of opponents i speak about
