其實曼城藍月亮綽號跟隊徽毫無關係 只是隊徽是藍顏色而已 據央視體育頻道報道 隊徽裡的 金鷹取自於曼徹斯特市的市徽，盾牌下方的三斜槓代表了曼徹斯特市的三條河，上的輪船代表了曼徹斯特大運河，老鷹象徵是全力與地位，鷹頭上有3顆星星，代表著要拿三冠王。

而這個暱稱的由來與其俱樂部的吉祥物Moonchester

曼城球迷的喜愛,在曼城的成績有所提高的時候，球迷們就會高唱“月亮升上湛藍的天空

《Blue Moon》

歌詞

　　Blue Moon

　　You saw me standing alone

　　Without a dream in my heart

　　Without a love of my own

　　Blue Moon

　　You know just what I was there for

　　You heard me saying a prayer for

　　Someone I really could care for

　　And then there suddenly appeared before me

　　The only one my arms will hold

　　I heard somebody whisper please adore me

　　And when I looked to the Moon it turned to gold

　　Blue Moon

　　Now I"m no longer alone

　　Without a dream in my heart

　　Without a love of my own
