Definitely a good thing that we are going to get some big teams playing against each other, it became a little bit boring when we are talking about something bigger, it wasn't something that we can agree with that easily, it is not going to be a fine situation and we need to do better.
Think about it, we have seen big clubs just destroy the smaller clubs in groups so far, which didn't make that much good tv, we still watched it, but I bet that when these big clubs play each other, there will be a lot more people tuning in. That means bigger audience, that means bigger tv rights deal, that means more tickets (or more expensive at least) and that means more merch sales for teams too.
These all point to making more money for every team and that is why I enjoy this new group stage system. Plus, you get to play two more extra games on top of all that, which means a lot more money too, and every team that joins this group stage, will make a lot of money and will do just fine.
The part where we are going to see big teams going against each other in the first round of the UEFA Champions League is actually what makes the new format very interesting if you ask me. The first time I saw how the new format, I was displeased with it as I thought it'll make the competition boring but considering the fact that we're now going to watch more matches as well see big teams clash against other big teams in the first round, I think we're likely to love the new format than the former.
As a Real Madrid fan, seeing that my club will have to play against big teams like Liverpool, AC Milan and even our last season UEFA Champions League final opponents Borussia Dortmund in the first round of the competition makes it more interesting
