The Busby Babes: the flowers of Manchester.
Line-up (2-3-5): Harry Gregg; Roger Byrne, Bill Foulkes; Duncan Edwards, Mark Jones, Eddie Colman; David Pegg, Liam "Billy" Whelan, Tommy Taylor, Dennis Viollet, Johnny Berry.
Notable squad players: Jackie Blanchflower, Sir Bobby Charlton, Albert Scanlon, Kenny Morgans, Geoff Bent, Ray Wood.
With the teams of 1968 and 1999 coming third and second in our power-ranked order, that makes the Busby Babes No. 1.
If Busby's second team had the greater individuals, and the treble winners were the more complete team, then the Babes were said to be somehow superior to both their successors in both ways.
In Duncan Edwards, they had a player thought to be destined to become one of the very best, while the likes of Taylor, Byrne and Colman were exceptional players in their own right.
Blanchflower, young brother of Tottenham Hotspur great and player-turned-journalist Danny Blanchflower, could add a touch of finesse in place of Jones, who was the Babes' primary enforcer alongside his fellow half-backs Edwards and Colman.
A half-back was a position that has since become obsolete, which worked out as a sort of hybrid of a defensive midfielder and centre-back.
Byrne was the Babes' captain at full-back and one of the most respected defenders of his day, often paired with Foulkes, who would go on to complete his team's European mission in 1968 and take on his friend and mentor's role as leader. Bent was their able and ready back-up.
Full-backs in those days made up a two-man last line of defence, behind which Gregg would tend to the goal.
The Northern Irishman was dubbed the hero of Munich for his bravery in saving others from the crash site, and he was equally courageous and bold on the pitch, demanding others lift their game or inspiring them to do so.
Before the team was lost on the tarmac in Munich, they were competing for three trophies and coming into their own on the international scene.
In 2008 David Meek recounted some contemporary opinions on Duncan, Byrne and Taylor from an England national team colleague, Jimmy Armfield, and manager Walter Winterbottom for The Guardian.
Armfield on the three Babes:
With Duncan Edwards, Roger Byrne and Tommy Taylor in the team, I believe England would have reached the final of the 1958 World Cup, and probably won it. Playing in the same team together I can still see this powerful figure stalking the dressing room and at the time I would think: 'I'm glad he's playing for us.'
Winterbottom on Edwards:
Duncan was a great footballer and he had the promise of being the greatest of his day. He played with tremendous joy and his spirit stimulated the whole England team. It was in the character and spirit of Duncan Edwards that I saw the true revival of British football.
There are some who have questioned whether Bobby Moore would have been such a key figure for his country, let alone captain, had Edwards not been killed, as per The Telegraph.
Sadly, such thinking is entirely academic since the half-back never got the chance to fulfil his promise.
Taylor was the quintessential English No. 9, leading the line while maintaining a prolific goal-scoring record for his club and country. Around him would swarm the likes of Billy Whelan, Dennis Viollet and wingers such as David Pegg, Kenny Morgans, Johnny Berry and Albert Scanlon.
Like Sir Alex's United sides at their best and most fluent, the Babes overcame their opponents through excellent movement, positional fluidity and a fearsome appetite for goals in attack.
The Busby Babes were the team that launched the modern United legend and, according to many of those who watched them and played with them, they haven't been bettered in the club's colours since.
It's easy to forget that going into the 1958 European Cup competition, it was the Babes who were the favourites to win in the eyes of many in Europe, not Real Madrid who were already on their way to completing their historic five-in-a-row clean sweep in the tournament's early years.
While the 1968 team may have taken on their European baton and the 1999 champions completed their full-frontal assault on the trophy cabinet, neither would have needed to undertake such assignments to finish the Babes' work had Sir Matt's first great team survived.
