Does their relegation now make pompey the lowest ranked team in English football to have previously won the FA Cup ? if not, who is it and where are they ?
Yeah I don't know if it's actually Oxford University but I imagine a few of the early FA Cup winners are very low down the leagues, if they still exist at all.
The same Oxford University team that won the cup never stopped existing, though it seems they don't participate in the English football league system now. http://en.wikipedia.org/wiki/Oxford_University_A.F.C.
The other early winners, like Wanderers FC, Royal Engineers, and so on, all seem to have dissolved.
How about the Corinthians?
