I think what you say is true Puck, except for Keane's time at Forest where he'd probably be seen as the most offensive of the 3 (maybe right at the start of his Man Utd time too to an extent). Even though he didn't play alongside a more defensive partner at Forest (and most often in the end he was alongside a less combative one, Scot Gemmill even though Keane mainly played fairly at that stage and Clough mainly insisted on it - he and Ian Woan were once substituted for misbehaving although it was dissent IIRC). At that time Clough didn't play anything like an outright DM though, wheras arguably McGovern was a sort of anchor in the 'glory' years and him and Archie Gemmill together was pretty good defensively as well as with the ball, if not a partnership that scored many goals or was required to. Vieira and Petit was a 50/50 partnership maybe (but with differing styles) but certainly Gilberto sat back more than Vieira. I think Keane was a better player going forwards at Forest actually, and a big fee was paid by United, but ofc at United he really developed the aspects of controlling the game and decision making that comme referred to. Vieira was the most skilful in my view I will say, if not the best in every attacking aspect.
