They had a relatively good period under the Pisscan/Gill/Riley/Clattenburg/Webb organisation, but before and since they have been nothing to write home about.
They have had the media lauding their every move since the formation of the club, and have attracted money because of it. In terms of the football on the pitch it's all been long-ball stuff, hoofing it up the other end (saw highlights of one of their games recently, Schmeichel did nothing but outdo Jordan Pickford with his booting up the field), so what this mythical u*ited way is supposed to be a reference to I have no idea.
Mega-succes is something that happens now and again in football, no club will ever reign supreme forever, it just isn't like that, and the rags should look at the likes of Preston North End for giants that had their day long ago and have since faded into relative obscurity.
