What does the 3stars above the man city football club logo represent?

The three stars above the Manchester City football club logo are only decorative. The ship represents the Manchester Ship Canal, and the three diagonal stripes stand for the city's three rivers: the Irwell, the Irk, and the Medlock. The motto at the bottom, Superbia in Proelio, means Pride in Battle in Latin.
