What is the definition of Manchester Infection?

Ah, the 'Manchester infection' - a term that's as catchy as it is unsettling, but let's break it down. It's like when you catch a whiff of stale pizza from a friend's house, but instead of just saying, "My taste is off," you're calling it the 'Manchester infection'. It's the insidious spread of Manchester City's legendary attacking prowess, likened to a virus, infecting local football clubs with its relentless, over-the-top flair.
