I did an experiment in FM by creating the most belligerent player possible, confrontational, controversial and dirty on the pitch, but still one of the best players in the world. Something amazing happened. When Liverpool signed him from Sunderland, not 2 weeks into his contract, Dalglish fined him for a red card. This made the player disproportionately angry and he, I didn't even know this could happen, took his case to some board in order to terminate his contract due to unfair treatment. It didn't work the first time, but a few years later on the third try at doing it he managed to get his contract legally terminated and then signed for Milan on a free transfer. He averaged 2.66 red cards a season at Liverpool.
