one possible semi final matchup that now seems a dim chance is Betis vs Sevilla.. because Betis is down 2-0 from the first leg and there chances are not too great given how strong Atletico are. Sevilla drew the first leg vs Zaragoza 0-0 at La Romareda! now we all know Barcelona vs Real in the semi final so i dont gotta mention that.   Then if Real and Atletico make the final that would be intense! Malaga vs Sevilla in  final in an Andalucian Derby, or a match between 2 big boys Sevilla and Valencia in the final (though Valencias chances are also slim) i would personally love to get Sevilla in the final so we could possibly get revenge on those guys for there  controversial 2010 elimination of us. and a semi final between the 2 underdogs Zaragoza and Betis would be nice!

You forgot Atletico Madrid and Barcelona in a potential finals match up. DAAAAAAAAAAAMN
