Smooth sailing for Man City. Copenhagen just wasn't a match for them, the Danish team is not in its peak form, even in their league they lost 3 out of the last 5 games.
City is a massive favourite to win the Champions League. Odds are as follows:

I agree with the table display above where the big 4 strong candidates include Manchester City, Bayern, Madrid and Arsenal. Well, for Arsenal, I will not underestimate them this season, who have made slight improvements in a positive direction. But because in Leg 1 they were behind against Porto, in Leg 2 they will carry a heavy burden. If they succeed in turning things around, perhaps what I hope will materialize as part of the strong candidates this season joining Manchester City, Bayern and Madrid. We also still have Inter and PSG both as unexpected options because they are both strong and experiencing positive trends this season.
Actually I partially agree with the first top five teams, but I don't actually think arsenal is better than inter Milan, so in my opinion, inter Milan should had been ahead of them, and of a truth, this arsenal team is quite good, but we need to understand that experience is an important player after quality in a competition like this, and Arsenal we all know have that tendency of not being reliable in major competition especially in the champions league and I don't really sees them going as far as the semi final stage of this competition, because experience is very important, and that is what this particular arsenal team lack.
I even had other different thoughts. Namely, I prefer to place Inter Milan over Bayern in third place in the table. Last season Inter Milan proved their quality. And this season is no different. Even in Serie A, Inter Milan is almost certain to become champion there. This shows how consistent this team is in the domestic league and also in big competitions. But if you look at the depth of the squad then I also agree with the order in the list. Because after all Man City, Real Madrid and Bayern are the 3 big clubs in Europe at the moment.
And I also agree that Inter Milan can actually be said to be better than Arsenal. But this is the Champions League and many surprises in this big competition can happen even to teams that are considered weak and can go further if they are lucky.
