My players (Rene Adler and Lucio) have recently complained about the lack of discipline at the club (Arsenal.) How do I go about improving the discipline of the players? It came after Bacary Sagna picked up another yellow card. He has 5 yellow cards in ten appearances. On my manager profile, it says I have 70% squad discipline. I am playing with More Aggressive tackling, as I play a possession style football and the team needs to be aggressive to get the ball back.
