My guess for the round of 16:
Group A: Benfica, Manchester United
Group B: Bayern Munich, Paris St-Germain
Group C: Chelsea, Atlético Madrid
Group D: Juventus, Barcelona
Group E: Sevilla, Liverpool
Group F: Manchester City, Napoli
Group G: Monaco, Leipzig
Group H: Real Madrid, Borussia Dortmund
I agree. We will likely top our group.
We need other English sides to win their group as well. That is because we cannot draw an English side in the round of 16.
If it ends (first team group winner):
Group A: Manchester United, Benfica
Group B: Bayern Munich, Paris St-Germain
Group C: Chelsea, Atlético Madrid
Group D: Juventus, Barcelona
Group E: Liverpool, Sevilla
Group F: Manchester City, Napoli
Group G: Monaco, Leipzig
Group H: Real Madrid, Borussia Dortmund
Then we could get: Benfica, PSG, Atletico, Barca, Napoli, Leipzig, Dortmund (2/7 chance of a really bad draw)
If we finish second then we would get: Juventus, Bayern, Monaco or Real Madrid (3/4 chance of very bad draw)
