I think Keane's leadership qualities would put him over them all. Despite being even more hotheaded and reckless with his tackles than Scholes was in his younger days. I mentioned in a previous thread how United fans used to joke that Scholes "made his obligatory rash tackle of the game/month/season" as years progressed.
Yeah, the guy was also just a dominant force. I've said here before, but he's really not accurately rated because : a) people don't like him , and b) people don't know how to asssess or value his impact/abilities. So we hear things like "leadership" and from people who don't know what they're talking about, he gets reduced to a "thug." The guy is one of the best defensive/tactical minds
ever at his position. Whatever the club needed to win, he was capable of morphing his game into being that solution. He was also capable of orchastrating and elevating his teammates to a degree we've rarely seen.
Without going on huge rant, defensive (or minded) midfielders are horribly assessed/valued by fans and by the football world in general. They don't know what they're looking at.
We're now getting new statistics (such as "Packing") that making it a little more quantifiable, but the paradigm is still fully invested in what they've digested as football truths.
In an interview with the Daily Mail to coincide with the imminent release of his autobiography, Gerrard was asked to rank Keane, Frank Lampard, Patrick Vieira and Paul Scholes in order and he had little hesitation in naming the Irishman as his top pick.
"Roy Keane No 1. The rest? They’re all different," he stated.
'nuff said.
