If you don't get top marks in this Champions League quiz, you should hang your head in shame
Fans of the Champions League should be getting a very high score in this.
This quiz isn't difficult to figure out.
We're giving you two football clubs and you just have to tell us which one has won more Champions League/European titles from 1952 up until 2017.
Anything over 12/15 is an excellent score.
Best of luck and let us know how you get on.
