I've being following the FA Cup for over 35 years and only found out today that a Ref can only officiate the final once in his career... Blimey! Where Have I been.
Anyhow even though Chelsea knocked United out I have a real distaste of Arsenal... so my prediction is:
I do like to be proven wrong on the rare occasions that I am ;-) Yesterday not so much. I was really taken aback, knowing that Arsenal can play but Hull City (Random) would have made a better showing than Chelsea. Well done on the predictions though.
