Our Champions League obsession continues. On this piece for New York Times Goal, we take a deep look at the the history of Champions League final matches – all 55 of them played since the 1955-56 season, when the tournament was known as the European Cup.

We've also highlighted the performance of Spanish and English clubs in anticipation of the 2011 final between FC Barcelona and Manchester United.
