This is football. Unlikely things are made reality frequently. Pochettino is probably not as unlikely as some think, but of course he's going to need assurances before risking his reputation turning up at the managerial graveyard that is VP.
For Villa to progress, we are going to need some unlikely things happen to get past the glass ceilings we'll come up against. It's a challenge for the owners to demonstrate that they can make this happen. They lost their first major battle with not being able to keep Joe. It's time for them to show they mean business with making Villa a force and not just a club happy to be in the EPL.
