I saw your match and I think there was no reason to lose. You had the quality, right tactics and training bonuses. That was really bad luck.

Returning to the topic, most times I do the required number of training but very low intensity and/or on one player of substitutes.
Sometimes I don't do that number of training especially if I have the training bonuses 10%.
I didn't notice any significant effect on matches. ( most probably I lose due to bad luck or wrong tactics. )
Also I don't believe that live animation is what happens really. I think there are scenarios and the game chooses one of them. I say this because when I use through the middle long passing, I see my wingers scoring and I rarely see long passes.
