Right.
Let's start with the first certainty. The Conference League place is actually supposed to go to the winners of the League Cup. We know the final is Liverpool v Chelsea. When the winner qualifies for a higher ranked competition then the place will drop to a lower league position. Liverpool are going to make the Champions League places surely, and you would be staggered if Chelsea didn't at least make Europa League considering their current points total.
So assuming that, the current position would be Manchester City, Liverpool, Chelsea, and the fourth place finisher into to the Champions League, fifth into the Europa League, FA Cup winner into the Europa league, sixth into the Conference League. All Europa and Conference positions would be directly into the group stages I believe, but I need to research that.
Let's next consider the Champions League. Liverpool City Chelsea and Manchester United are all in there. If any of the first three win it then they will almost certainly qualify by league position, so it shouldn't make any difference. United winning it if they didn't make fourth place becomes a fly in the ointment as there would be five teams in the Champions League and therefore only one in the Europa and the Conference can only ever be one team for England because of the high coefficient guaranteeing extra places in the higher competitions. So we don't want United to win the Champions League unless they also finish fourth (if we finished fifth right behind them).
FA Cup. We really could do with a Manchester City or Liverpool winning this. Or Chelsea would be okay. Ideally any Champions League qualifier winning it, bar Manchester United, West Ham or Spurs if we are trying to beat them to fourth. So let's hope they all lose in the cup.
Europa League. We absolutely do not want West Ham winning this competition. That would see them getting a Champions League spot, which hugely restricts our chances of getting in.
Conference. We equally don't want Leicester winning this competition. Automatic Europa League spot.
That's all I have for now. Obviously will add to it as the race continues like I did three years ago, as it is stuff I find interesting.
