The current club crest was adopted in 1997, a result of the previous crest being ineligible for registration as a trademark.[Full citation needed] The badge is based on the arms of the city of Manchester, and consists of a shield in front of a golden eagle. The shield features a ship on its upper half representing the Manchester Ship Canal, and three diagonal stripes in the lower half symbolise the city's three rivers – the Irwell, the Irk and the Medlock. The bottom of the badge bears the motto Superbia in Proelio, which translates as Pride in Battle in Latin. Above the eagle and shield are three stars, which are purely decorative.
City have previously worn two other crests on their shirts. The first, introduced in 1970, was based on designs which had been used on official club documentation since the mid-1960s. It consisted of a circular badge which used the same shield as the current crest, inside a circle bearing the name of the club. In 1972, this was replaced by a variation which replaced the lower half of the shield with the red rose of Lancashire. On occasions when Manchester City plays in a major cup final, the usual crest has not been used; instead shirts bearing a badge of the arms of the City of Manchester are used, as a symbol of pride in representing the city of Manchester at a major event. This practice originates from a time when the players' shirts did not normally bear a badge of any kind, but has continued throughout the history of the club.[51] For the 2011 FA Cup Final, City used the usual crest with a special legend, but the Manchester coat of arms was included as a small monochrome logo in the numbers on the back of players' shirts.[52]
