Matchday 1 is now over, and we're bringing you the latest rankings for all the Champions League participants.
There were some great matchups and great matches in this first round, and they give us an idea about who is in the best form early in the competition. Rankings will be based on a variety of factors.
The club's recent history in the competition and overall quality play a role in how it would be ranked heading into the competition.
The likes of Bayern Munich, Barcelona and Real Madrid would be at the top of the rankings, considering their status as favourites. The German side would lead the pack thanks to its status as reigning champion.
Likewise, Viktoria Plzen and Steaua Bucharest would be among those at the bottom of the rankings when looking at similar factors.
What changes the rankings from the opening matches are the results. Strength of the opposition, the group and whether the team is home or away are underlying factors, but, ultimately the result dictates who stands where in the rankings.
For example, Juventus' first ranking will take a hit given their draw to FC Copenhagen, while the Danish club will get a boost.
There's still a long way to go for some of these teams to change their position, but here's the latest Champions League Power Rankings after the opening matches.
