I did mention those missed chances

but in the end they are irrelevant. It's such intangible arguments all supporters of this side put forward and such factors can never be measured - such as the fact that Barcelona are always the better footballing team win-or-lose.
Rather than looking at all the finer points it is much easier to look at the plain statistics. In 10 years time people who never witnessed this team will look back at the records and if as you say the 'football-wise Barcelona have been the best team in Europe' there will be a glaring contradiction.
Look at the performance of finalist in the knockout phases since the revision of the tournament:
2005/2006
Arsenal: 3 wins, 3 draws, Goals: F4-A0
Barcelona: 3 wins, 3 draws, Goals: F6-A2
2004/2005
Liverpool: 4 wins, 2 draws, Goals: F9-A3
Milan: 5 wins, 1 loss, Goals: F8-A3 (Note: only counted Inter 2nd leg as 1-0 not 3-0)
2003/2004
Porto: 3 wins, 3 draws, Goals: F8-A4
Monaco: 3 wins, 2 draws, 1 loss, Goals: F12-A10
Firstly, Barca look no more impressive than Arsenal from this year. But we see that 3 wins and 3 draws is more of a common occurance not one of a team who has dominated. The goals totals this year are the most worrying. People assumed the two previous winners were defensive but what of these 'attacking' sides? On paper these stats paint them as the most dour.
From that list it is clear to see that the Milan team of last year stands as the most accomplished as dominant with 5 wins and only defeat and goals conceded in that final PSV game. Had the HT score in Istanbul stood I think we'd have been looking at one of the greatest CL teams of all-time being winners two years before and league winners coming into the tournament.
