I know some of the clever, I alone understand how football works, knowledgistas on here will tell me how wrong I am and how I'm a knaa nowt, iggerant clownshoe, but the situation we are in can be analogously described thus:
If I decide I want a new pair of shoes, I don't throw my old pair away, then wait a month before I get around to going to buy a new pair, because there's a chance that the shop won't have them in my size, which'll mean that I'm now barefoot with no shoes.
I'm gonna be in pain.
I'm gonna be well off my usual pace.
I'm gonna get left behind very quickly by all sensibly shod people.
