So
For those interested, I have put together some detailed analysis of the situation regarding who could be in pot A/B - the good news is, as far as I can see, it is virtually impossible for us to not be in Pot B if we don't win the league as we are currently in 12th, with only 3 teams behind capable of catching us up if we go out now (Utd/Chelsea/Napoli) - and of the 11 teams ahead of us, 4 teams are almost certainly going to win their league and go into Pot A, with City being a 5th IF we don't win the league, and then of the remaining 6, Sevilla are currently not qualifying for the next seasons (and at least one of Arsenal/Utd/Chelsea if they all catch us not being in it either probably). I think for us to be in Pot C, we'd have to lose both matches vs Porto, AND:
1) Not win the league
2) Have Sevilla get 4th in La Liga
3) Have Porto not win their league
4) Have Napoli get 2 more points in the europa, not win it, and qualify
5) Have 2 out of Arsenal, Utd or Chelsea finish top 4 and win at least 2 games each (and not win Europa/Champo)
Which would give us, Pot B being Real/Atletico/(Borrusia or Bayern whomever comes 2nd) / Sevilla/ Porto/ Napoli/ and then 2 out of (Arsenal/Chelsea/Utd) with us then being the highest ranked team to miss out.
If any one of them doesn't happen, than we are guaranteed of at least the 8th spot in Pot B.
