Matthias Riisgaard is a former player of FC Dumdideldei. He was most famous for not playing a single match with the club in 4 seasons before retiring. He was part of a novel training technology experiment called osmosis training, and was a very promising team member in that group. During his time in FC Dumdideldei, he successfully improved his scoring skill from inadequate to passable and beyond. When he was about to further develop his skill to solid, the training experiment was suddenly stopped by the Hattrick Football Association (HFA) after some accusations of illegal practices. Matthias had to abandon his dreams of becoming a professional football player and did studies in infomercial hosting. Since then, he has been unsuccessfully pushing his new professional passion for 25 hattrick years.
