United have their own Wembley appointment for the Champions League Final with Barcelona on May 28 and UEFA's demands for two weeks of protection for the pitch before that game is why the FA Cup Final is, unusually, being played before the end of the Premier League season.
City face Stoke City at Wembley, by which time the day's league games will be over and United, should they draw at Blackburn Rovers, will be celebrating their 19th title and 12th under manager Sir Alex Ferguson.
Should Manchester City land their first major trophy since 1976 after decades of living in United's shadow, it would be a reminder of the second and last time they won the league in 1968.
Last Sunday's 2-1 win over second-placed Chelsea gave United 76 points against the London club's 70 with two games remaining.
City's midweek win over Tottenham Hotspur took them within two points of third spot which offers automatic progress to the group stage of the Champions League.
The team in fourth goes into the qualifying round playoff for Europe's elite club competition.
"Everyone has said this is not a good United team, that we are not this or not that," Ferguson said this week.
"But we have scored more goals that anyone else, our home form has been magnificent, we are undefeated in Europe, we are in the Champions League final and we will win the league by getting one more point."
