The impressive performance of Real Madrid deserves to go with the trophy this season, but what many are thinking will be the barrier to their victory is Manchester City, but to me, I can say that Real Madrid will surely win the trophy, although all how you rank those teams up is looking more like a sure prediction because it might work that way, and Barcelona deserves their position. You put them as the 6th because of their poor performance this season. I see no reason that Barcelona will even think to reach the semifinals because their performance is not up to the standard, but we can’t just conclude.
Inter Milan and Arsenal performances are all the same, but if you compare with effective consideration, you will see that Arsenal performance is somehow more than Inter Milan, but I believe more in Inter Milan than Arsenal. The positive you kept Bayern Munich as the 3rd is also ok because they are also trying their best to maintain the standard, but they should never think of winning the trophy, which is very heavy for the team.
The UCL round of 16 is sef to kick off next month and for some teams, it's going to be a serious tussle and for some it'll be a minor jump through to the next stage. Judging based on team strength, City has a better chance to advance than Copenhagen, so does PSG, Dortmund and Bayern. For the remaining fixtures, the teams are strong and the result is just unpredictable.
Arsenal and Porto are in good form, same performance range, the probability is shaky, thesame with Napoli and Barcelona. For Madrid and Leipzig, one would say Madrid are in a better position to advance but the German side shouldn't be underrated though, they're also good in their own way. For Inter and Atletico, it's going to be a serious battle, none of them would allow the other to just go freely without making it tough. Hopefully these teams would use their home advantages wisely and to the best of their ability too.
