Actually the
Draw only determines who plays who
Then UEFA and the clubs (and TV companies?) decide who will play on which night, to maximise media coverage and fit in with clubs' existing domestic schedules.
But note that MC-CHE has mysteriously disappeared from the TV schedules on both Sky and the PL's websites. This leaves space for Sky to show one semi on Sunday at 4, and BBC to show the other on Saturday evening (and I suspect BBC, having first choice, would probably choose WBA-Pompey?)
So MU will prob play Wed 9th in the CL, so Chelsea will prob play Tue 8th (unless they draw United!) so their City match will move back to Sat 5th.
