Getting draw is unpredictable. You can't blame PSG for getting draw against a lesser team than PSG. It's too early to say that. Anything can happen. Just because manchester city was showing a good performance in EPL and it doesn't mean city can win champion league easily. Napoli, real madrid and so many big clubs have been still participating in the champion league. I will not underestimate another team but you must remember that if city many times city got fail to get champion league
PSG play in Ligue 1 without much competition, and City build their character in the Premier League matches all the time. You should also not call Benfica a weak opponent, especially when they play at home. There are not so many applicants for the title, these are Real, City, Bayern (this is my opinion). PSG still place too much importance on this title and that is what prevents them from winning to a large extent. The rest of the contenders look mediocre, or if they play well in the group, like Napoli, then you need to look at their results in the playoffs.
Departing from the league of each favorite club such as Manchester City, Real Madrid, Bayern Munich, Paris Saint Germain. I choose one of several teams from the league they play in their respective countries. I mean, the level of competition in the Premier League can't be compared to Ligue 1 which obviously belongs to Paris Saint Germain. But here seen from the performance of the club itself. To be honest, I still believe in Manchester City more than Paris Saint Germain. Why? yes because according to their performance they have not been able to reach a higher level like in this Champions League.
I'm not trying to belittle any club, but I'm purely looking at the way they play and also in terms of mentality, because that's very important for a competition that has bigger stakes.
The most experienced team in champion league also have more advantage over the rest teams especially from the semifinals. For now I can't predict who will be lifting up the trophy as no team should be down graded in this league. At semifinals then we can see clearly who will be the winner. The big teams like Real Madrid is a threat to other teams. Although all the teams will play their best but just a little error might be their end.
Now the competition is still in the group phase, I would say the competition is actually in the knockout phase, except for the clubs who are in the Hell group like in group C, which consists of Bayern Munich, Inter Milan, Barcelona and Viktoria Plzen (which I think they are unlucky) . We can see later in the knoutout phase the favorite clubs will fall one by one, that's the real competition. Because in the group phase there are still many opportunities for them to survive because they played 6 rounds of matches.
