Mirth close. But worst are probably Chelsea after winning in 2015-16. And obviously Blackburn when they won and lost Shearer.
By the way, lost in this constant criticism of how Arsenal play football is that Chelsea have basically admitted to cheating their way through the 2010s, amassing a large squad of superstars and using them to win trophies to grow their profile and income. That for me should be the focus of discussion, but I suspect the mainly Pool/United pundits polluting football see City/ Chelsea as convenient parasites who create a buffer against their real rivals.
