For me this is a very difficult thing. First, I admit I can't view our club in a very realistic fashion. I'll always put them ahead.
Another reason I have difficulty is that when we have played Bayern and Barca the last couple years, I think we are pretty much on part with Bayern. The Barca matches show just how different they play than the PL sides. You touch any of their attacking players and they go down. There is never an attempt by them to stay up and press forward. What has hurt us a lot is that at the start of the matches we rack up a ton of fouls and then our team has a hard time surviving without yellow cards flying left and right. I realize it is part of their style, so from that end, I understand, however part of our style is to be physical. For some reason the Champions League officials always seem to go against physicality. When PL officials are used for the other matches, they let them play a lot more. I'd like to see the records of the various leagues with PL officials versus their records with other officials. It may show that there is a difference. One thing that I like when I watch Real play is that they aren't a bunch of divers. So while I do think that I would rate them above ours mainly due to results and that they have a team filled with world class players, I do think it would be a very entertaining matchup.
The draw is always something we will have to fight through. With any luck this year, we win our group and won't have to face PSG, Real, Barca, or Bayern in the knockout stages. Then we have advanced to a point that our team should be given a better result. If we finish 2nd in group, we are going to face the same things we have the past two years. Does anybody really think that Juve was the 2nd best team in Europe last year? I don't. But they did what they had to do in order to make the finals.
