At the moment, the last Fifth Round tie in this season’s FA Cup is going Manchester United’s way. In the Sixth Round, they would face bottom-placed Norwich City, away. United ought to win. As for the Bitters, they’re away at Newcastle United: a bit of a harder tie, but they too ought to win.
At which point we can dispense with a semi-final draw and just put us against them. Every single time the two Manchester clubs have both reached a semi-final, they have been drawn together and this will continue until eternity.
Equally, should the Magpies actually knock ut the Bitters, they are the one team in the semi-final draw that United will not be paired with.
Accept the word of one who knows.
