 Although there are no strict rules, derby games in France are commonly divided into three categories - derbies, local derbies and classicos (originally a Spanish expression).A derby is a game involving two teams from neighbouring cities, a local derby would involve two teams from the same city and a classico involves two teams from two cities quite far apart geographically which have developed a great rivalry along the years - such as PSG and Marseille in football for example.Local derbies are extremely rare in France, especially in football.
