For new players, start by playing 'Kick Off' matches against the AI on a lower difficulty to get a feel for the game. Utilize the 'Skill Games' to practice specific techniques like shooting, passing, and dribbling. Don't be afraid to experiment with different formations and tactics in the 'Team Management' screen.
Focus on maintaining possession and making simple passes before attempting complex skill moves. Defensively, try to cut off passing lanes rather than constantly chasing the ball. Patience is key in both attack and defense. Watch tutorials within the game and online to further refine your skills.
