With Manchester United and Chelsea matching up tomorrow for an all-English final in this years UEFA Champions League, I wondered how often the major continental cup finals have had two teams from the same nation. This list shows all of the continental cup finals around the world that have matched up two clubs from the same nation.
The winners are in bold and the numbers in parenthesis are that year's domestic league position for the clubs involved.

CONMEBOL Copa Libertadores

It's interesting that outside of the two South Korean finals in Asia and the Costa Rican final in CONCACAF, the lower placed side in the domestic league wins every time. That's 9 out of 12 games where the lower ranked team has won.
The African and Oceania Champions League's have never had a same-nation final matchup.
Manchester United v. Chelsea is only the second 1-2 matchup in a final. Domestically second, Internacional beat league winning Sao Paulo in the 2006 Copa Libertadores. (I guess you could say that Pachuca v Chivas in 2007 was also 1-2, but I used the combined Apertura/Clausura rankings.)
The last all-English final in a European competition was in the 71/72 UEFA cup when Tottenham Hotspur defeated Wolverhampton Wanderers 3-2 on aggregate.
