BR - Some of the world's greatest players have participated in Europe's premier club competition, the Champions League.
All of these players on this list have left, or are leaving, their mark on the competition in some form.
There is a wide variety of reasons as to why players are on this list, with some achieving success over lengthy periods of time in the competition and others making maybe one or two significant contributions.
It's a Top 50 players list, which sucks because it doesn't leave any room for debate.
I can't say that anyone is missing.
