I don't trust Atletico in the final either but really want them to win the trophy. It will be good for Spanish football to have another team rival the big two and cement that position and then go on and do the same in Europe. There is no reason why a club like Valencia can't do the same if they get the right people at the club, so Atletico becoming Champions of Europe would hopefully inspire others in Spain to get their act together.
It would also be good for us especially if we win the double as although Atletico would be champions of Europe we would still be the best in Spain and have beaten them 7 times of the last 8, so what does that say about us? If Bayern win it then they will have their 2nd treble and with Ancellotti next season could go back to back, in fact I think they would be more of a threat with him in Europe. If Real win it then that would be 2 from 3 matching what Pap's Barca achieved and Ronaldo would take home another Balon d'Or both of which would be unbearable.
I don't want City to win it either as they are completely average and have had their success handed to them on a plate whilst others like Atletico have had to fight hard for everything they have got. Any club could do what City have done with their owner financing them, only a special club like Atletico could do what they are doing right now.
