Wednesday night sealed it. There will not be a more seismic post-war FA Cup final than next month's.
Manchester City will arrive at Wembley as champions and in the final of the Champions League. They are odds-on to emulate United's Treble 24 years ago. United are the best-equipped team to stop them.
City look an unstoppable force, a team with best-in-class in goal, in defence, in midfield, up front and on the touchline.
