HH, the fact you think the first line doesn't scan, although I may have to disagree with you over that point, is of little relevance. This is a song that would hopefully be belted out by 50,000 Liverpool fans around Anfield, and it's not an entry for the National Poetry Competition. Does every Liverpool song scan perfectly? I think not.
And the reason we're currently sat atop the PL is down, in no small part, to the teamwork, work rate, ingenuity and, perhaps more importantly, the goals from these four players, our new attacking unit. So I think they're very much entitled to a song of their own, to show them how much their input so far this season is appreciated by us all. And I believe the fact that they gel so well together as a foursome within the larger team negates your rather fatuous "best midfield in the world" reference.
As for your third point, someone on RAWK has honoured you with the mantle 'Scribe', so please, in future, think before you write.
Anyway, back to the wine.
