A good strategy is to train the young fast trainers and to play with the old ones (or the slow trainers).
The raise after the game has nothing to do with the performance or the difc. of the match or the Q of the oppo.
Play friendlies with easy team so you can win and get the blue pack.
This is an example from my guide - a friendly game against Morinho and against an easy team. Same progress.
