Nah, feck it, it was Keano.
Of course it was. In that team - with all three of them. Easily too.
Sensitive flowers don't like to hear this. But it's a facht.
In overall terms, it's Keano > Beckham > Scholes.
1. Keano: One of the best central midfielders ever. He was better technically than he's often given credit for. He was better in terms of "football intelligence" (as I like to call it: "knowing when to do what when and where") than he's often given credit for. And he had heart (which he IS usually given credit for) to an extent you rarely see.
2. Beckham: A specialist. Better at the sort of game he played than any player I've ever seen. And I actually struggle to dig up any historical counterparts (among those I haven't seen, up close and personal).
3. Scholes: A brilliant attacking midfielder with an eye for a pass which is rare but not unprecedented, a passing range which is top of the line, even historically (but not unprecedented by any means, and not really a feature of his game as an AM), a wicked long range shot - and a general propensity for scoring, i.e. an obvious penchant for finding himself in or around the box when it matters).
...and to add the fourth one: Giggs was a brilliant, very fast winger of the sort you don't see every day (but you do see 'em, historically speaking). He wasn't technically outstanding enough to give him access to the GOAT club in that department. Nor was he a goal scorer, although he certainly scored some memorable goals. He had a
drive (a quality not reflected in any stat) which was - and is - rare. An ability to influence the match, crucially, through his movements with the ball. Not many players have that
drive (though great wingers always have it).
He also had - which made him stand out in his own era (but it doesn't make him stand out in an historical context) - a great ability to whip in quickly delivered low-ish crosses which led either to goals or to a sufficient amount of confusion and disarray to create chances in the second movement (as it were).
