The glory of the same city

the theory of same city glory (n.) 同市光榮論 in Chinese
the glorious of the same city (adj.) 同市光榮 in Chinese

A joke that if one football club winning a decisive match or winning a trophy, the football club(s) of the same city / region can share the happiness and glory because of that.

This is advocated by a Hong Kong football commentator Wing-Kei Lee during a match with Everton against Manchester City in 2013-14 season. He is also known as Wing-Kei Li(verpool) , whose commentating way is sometimes unprofessional.

In 2013-14 season, Liverpool and Manchester City were the main rivalry and contestants for premier league trophy. The premier league trophy was not won by any Merseyside (The place where Liverpool and Everton football club locate) football clubs. In the decisive match with Everton against Manchester City, from a general point of view, if Everton defeats Man City, Liverpool will be adventageous to winning the trophy that the football clubs of Merseyside did not won before, therefore Everton should be motivated and stimulated for the glory of the same city to win this decisive match.
