Manchester United were put in their place and Manchester City are now one step away from heights only their FA Cup final opponents have reached before.
The Treble is 90 minutes from being seen again in English football after Pep Guardiola's side overcame their frustrations over refereeing calls to show once again that they are the better side in Manchester.
Two delicious goals from Ilkay Gundogan - prime Zidane in these months as his teammates have jokingly referred to him as - took him to six from his last six starts and earned City the FA Cup trophy that their play deserved.
His first, after just 12 seconds, showed City's improvement from when the teams last met. Then, Luke Shaw commented on how they had noticed how slowly their opponents started but here it was United asleep as Casemiro and Victor Lindelof both missed headers before Gundogan put his laces through De Bruyne's bobbling header to send the ball crashing past a hapless David de Gea.
