They haven't actually pulled out of the FA Cup rematch yet AFAIK so all this talk is premature. I think it's quite good of Villa to accept their game with Bolton to be re-arranged. There is no fixed amount of time that could be needed. Sagna's father died and he played on the same day/day after, didn't he? I also don't think it should be left in Bolton's hands when games should be played and nor would they expect it to. Bolton, as a club, feel these issues are secondary and I'm sure they are more than prepared to accept the consequences.
Man Utd played two weeks after Munich.
Für eure Sicherheit
Don't think it's fair for people to say to others to just "get over it". There's no set amount of time for something like that.
Personally though I think it would be more fitting to play and try to win it rather than give it up, otherwise it would just become a millstone around their necks. It was something suggested for us after Hillsborough, but it was agreed that it would be better to get out on the pitch.
We'll do it for Eduardo tbf.
The pulling out of the Cup has been floated for them, rather than put forward by them. Davies himself has declared the question irrelevant, and at this point he is correct.
