Training
Due to the time required to train players, use all your energy and coins before starting a training session. Focus on training the following skills in order: Power, Effect and Stamina. You can train two players at the same time.
Spend coins on upgrading special skills. Recommended skills are the Panenka, which tricks players in online matches, as well as Foot Change. They are not effective in multiplayer mode against real players. Use them in single player modes.
