I like the fact that you said it's your game prediction else I will say you just underrated the Champions League perhaps there are other things you look into to make this conclusion but they are lacking in quality teams if you don't include Real Madrid, I don't like Manchester City but they are among the top team I look forward to their games and likewise Napoli, your favorite teams were all English teams, you forgot to include other teams from other parts of the domestic league's Championships.
There were so many mixed emotions last season, so many clubs I was looking up to all failed me woefully and I was embarrassed by Real Madrid particularly but this time, I think there will be a lot of changes since teams like Arsenal, will make up the group this season, some of these teams will help clear way for my favorite team, just imagine Arsenal remove Manchester City in the knockout stage only for them to meet Real Madrid in Quarter final, that will be magnificent.
No mate, I excluded good team's from the list and such clubs like Real Madrid and Manchester city, both are champion leagues titles holders and Manchester City have won UEFA cup multiple time so both of them are excluded from the list and the list only includes clubs that are still coming up in their performance and willing fo make it totop 5 of top 3 but not first or second either ways, it is left for just speculations and how the clubs mentioned could possibly perform in this coming season haven't made good use of the transfer market.
I don't underate any of them in whatever way and I hope you understand my point of view and how I made up the list I posted in the earlier comment that you quoted above.
