5)Barcelona scored 32 goals on her way to the top, a record for a European champion. The previous best was Manchester United from 1999 (29 goals). But United played just 11 games instead of Barca's 13, so they still have the best average (2,63 against 2,46 for Barcelona).
This is "best average" for "champions league" days only, I presume?
Real Madrid scored 20 goals in 7 matches on the road to becoming the first ever European Champions (just semi-randomly checking the first ever year), which is a higher average.
Of course.
We can't compare the old format with the current one.
